Copyrighted publication

What is and is not permitted depends on the publisher. Most publishers allow you to use your pre-print or post-print versions in a closed online educational environment (digital learning environment). Use Sherpa Romeo to find the specific policy of the publisher in question. If the publisher’s policy does not allow the use of a pre-print or post-print version, the rules of Stichting UvO must be observed.

Stichting UvO and universities have signed an Easy Access Agreement. This agreement contains provisions on the reuse of extracts from published works in paper or digital readers, or individual reuse in Brightspace. Permission is no longer required for short extracts and medium extracts (up to 40 pages, but not more than 20% of the original publication) because TU Delft pays an annual fee to Stichting UvO for such reuse. However, the publisher’s permission is required for non-short extracts (more than 40 pages or more than 20% of a work) and a fee must be paid. [see infographic below]. You can submit a request for reuse via the Stichting UvO portal. In this regard, contact the Copyright Information Point.

"De Easy Access-regeling 2023 (wo)" by Stichting UvO

If you did not transfer the copyright to your publisher or no mention is made to this effect in the publisher’s agreement, you are allowed to use your own work at your discretion. If you collaborated with others (e.g. co-authors) on the work, you need their permission. If you published your work openly (Open Access) with a publisher, check under which Creative Commons license you published your work. If this applies to you, see “open publication”.

Online live session

You are free to show lawfully published work in an online live session that is a part of the curriculum, takes place in a closed online educational environment (such as Brightspace) and that only teachers, researchers, students (and academic staff) can access. If you need/want to upload/record the session in Brightspace, general copyright rules apply. For parts of books, articles and literature, the rules of Stichting UvO must be observed.

TIP: General copyright rules:

Ask permission when you want to use work for which you do not own the copyright.
Exception (no permission required): Right to quote.
The right to quote is subject to specific requirements:

You can only do so for a clearly identifiable purpose.
You may not quote more than is strictly necessary.
You must reference the source.
The source must have been lawfully published

Always reference the source.

Copyrighted publication

If copyright has been transferred to the publisher, printed copies of a publication are exclusively for your personal use. You can show your work without permission from your publisher, but you cannot distribute it to your students. You need the publisher’s permission to hand out printed pages.

Live session in a classroom

You are free to show lawfully published work in a live session in a classroom if it is part of the curriculum for teaching purposes. If you need/want to upload/record the session to/in a closed online educational environment (such as Brightspace), change "classroom" to "digital learning environment" in the search engine above.

Copyrighted publication

Copyright transferred to the publisher: what is and is not allowed depends on the publisher. Most publishers permit the use of pre-print or post-print versions on an open platform. Use Sherpa Romeo or the journal website to check this.

If you retained the copyright to the original work after negotiations with the publisher, you can use the original work at your discretion. If you collaborated with others (e.g. co-authors), you need their permission. If you don’t have the right to use the pre-print or post-print version, the general copyright rules apply.

Open multimedia

You can use open multimedia in accordance with the relevant Creative Commons license.
For work that is not licensed under a Creative Commons license, change "open" to "copyrighted" in the search engine above.

TIPS
1) Pictures with people
Before sharing work under a Creative Commons license, it must be clear that no portrait rights apply. If they do, you must have permission from the person depicted to show the photo/multimedia. Inform the person that the photo will be shared under a Creative Commons license.

2) Images of works of art
Before sharing work under Creative Commons, bear in mind that works of art such as statues or paintings are protected by copyright. You are not allowed to use pictures of a painting or statue that you took yourself without permission of the artist.
You are free to use pictures that you have taken of a work of art that is permanently located in a public space (e.g, public road, railway station, shopping centre or town hall). For pictures taken by someone else, you need to request permission. It is important that the work is depicted amidst its surroundings.
Museums and schools are not public places, so pictures taken in a museum or a school cannot be used under a Creative Commons license without permission.

Educational material

Educational materials belong to the University. If you want to use your own educational materials that you created at TU Delft, you need permission from the faculty for which the materials were created. If you want to use materials created while you were employed at another university, you need permission from that university.

Proper reference is always mandatory.
If the educational materials are published with a publisher, check the publication contract.

TIPS
1) Pictures with people
Two classes of rights apply to this type of images. The first is the copyright of the photographer and the second is the portrait right of the person depicted. In this case, you have to deal with general copyright rules, as well as with portrait right rules, which means that you must ask permission from the person depicted if the portrait was commissioned. If the portrait was not commissioned, you do not need permission, except if the subject’s interests are harmed (e.g. privacy). In case of doubt, we recommend always asking permission.

2) Pictures of works of art
Works of art such as statues or paintings are protected by copyright. You are not allowed to use a picture of a painting or statue without the artist’s permission. You are not allowed to use pictures of a painting or statue that you took yourself without permission of the artist. You are free to use pictures that you have taken of a work of art that is permanently located in a public space (e.g. public road, railway station, shopping centre or town hall). For pictures taken by someone else, you need to request permission. It is important that the work is depicted amidst its surroundings.
Museums and schools are not public places, so pictures taken in a museum or a school cannot be used freely, except if they are covered by a Creative Commons license. If you want to use a picture of artwork in your teaching, you may be allowed to quote it if you meet the necessary requirements.

Copyrighted multimedia

If you have signed an agreement or contract about the multimedia with a publisher/website/third party, the terms of this agreement apply, so you can check whether you still own the copyright. If you own it, you can use it at your own discretion. If you do not own it, you need to ask permission from the copyright holder (publisher/website/third party).

With shared work, you are not allowed to use the multimedia without the permission of the co-owner of the copyright. If you get permission to use it openly, you must always attribute the co-creator of the work as well. If you need/want to use the work on an open platform and do not own the copyright, the general copyright rules apply.

You can only do so for a clearly identifiable purpose.

You can use such material in accordance with the relevant Creative Commons license.
For work that is not licensed under a Creative Commons license, change "open" to “copyrighted” in the search engine above.

TIP
When reusing images (multimedia) licensed under Creative Commons, the Creative Commons conditions are applicable only to the copyright of the photo. If there is a person depicted on the photo, the Creative Commons conditions do not apply to their face (body posture, etc.) because of portrait rights. If it is not explicitly mentioned that the person shown has given the permission for their face (body posture, etc.) to be reused in the same way as the rest of the photo is licensed, you need to ask permission from the person depicted in the photo. It is always better to use Creative Commons photos without people.

Create your own open work

If you create open work, write your own texts and/or make your own pictures, images or videos (multimedia), the copyright on teaching materials produced by you as a teacher of TU Delft belongs to your employer. These materials can therefore be used for teaching and research purposes, unless other arrangements have been made. TU Delft encourages staff to and supports them in creating and publishing open learning material or Open Educational Resources (OER). TU Delft recommends using the CC-BY Creative Commons attributing license for these materials. For more information: see TU Delft Open Educational Resources policy.

If students were involved in creating the resources, they share the same copyright as you. We recommend making clear arrangements in advance. The Addendum Richtsnoer IER where guidelines for the relationship between universities and students regarding intellectual property and industrial rights from VSNU are stated, is applicable, and more information can be found on the TU Delft Intellectual property webpage.

Taking pictures

Works of art
Statues and paintings are protected by copyright. You need permission from the artist before you can use them. You can only photograph works of art that belong to the public domain without permission.
Artworks in public spaces, such as along public roads, in parks, in shopping centres and at railway stations may be photographed without permission. It is important, however, that the work is displayed in its surroundings. Museums and schools are not public spaces. If a work of art is in a museum or in any other place that can be entered free of charge, this does not mean necessarily mean that you are free to photograph it and use the picture.

In addition to all the above, you must also mention that the photo/image/work will be shared under Creative Commons license in the permission request form.

Pictures with people
If there is a person in a picture, portrait rights apply. If the portrait was commissioned, you must ask permission from the person depicted. If the portrait was not commissioned, you can use it without requesting permission, except if doing so harms the person’s interests (e.g. privacy). In case of doubt, we recommend always asking permission.
When taking pictures for teaching purposes, copyright accrues to these pictures which belong to you and consequently to your employer (TU Delft). When photographing people, request their permission by asking them to sign a form and notify them that you are going to share your work, which features their faces (body posture, etc.), under a Creative Commons license. You can reformulate and adjust the copyright permission request form as needed.

How to cite sources in new work   

You should always cite your sources properly, even if they are your own works. Failing to cite your sources properly will ultimately lead to accusations of plagiarism. There are three ways to include information from sources in your own text: you can quote, paraphrase, or summarise it.   

Quoting

If the exact wording used in the original document is important, you should quote the text, e.g. when the formulation used by the author matters. Put the quotation between double quotation marks to indicate that the words are not your own and add a reference. Important: long quotations of 40 words or more are considered block quotations and are formatted in an isolated block without quotation marks.  

When quoting other texts, bear in mind that:  

Too many quotations make your text difficult to read.  
Quotations must not be too long. Your text should mostly be your own, not a copy of what someone else wrote.

Paraphrasing  

Often, you will find yourself wanting to use ideas put forward in someone else’s work in your own. By paraphrasing other people’s ideas instead of quoting them directly, you can show that you understand the idea(s)in question. A paraphrase is approximately the same length as the original text.  
Paraphrase a text by describing the original idea(s) in your own words and adding a reference.  

When you paraphrase:  

Use your own words. You have to do more than just replace one or two words with a synonym!  
Make sure your readers are absolutely clear about which parts of your text are paraphrases, and which parts are your own ideas.

Summarising  

Summarising means describing a significant part of someone else’s work in a few sentences. This lets you incorporate a complete overview of someone else’s ideas into your own work. The rules for summarising are the same as for paraphrasing: use your own words and add a reference. 

Formatting your references

There are certain rules for the order of the references in your reference list as well as for the formatting of the references themselves. These rules are determined by the citation style (or reference style) you choose. A reference must contain enough information to be traceable. There are many different citation styles to choose from. Two examples are APA and IEEE. For more examples, please visit the TUlib website and APA 7th Citation Examples.  

Text generated by AI tools (such as ChatGPT)

you used when citing a ChatGPT response. If the tool allows you to create a link to the output, include this link in the reference, otherwise the full transcript of an answer may be included in an appendix or other supplementary material. Consult the APA 7th Citation Examples (Software > AI Tools) for formatting your reference.

You should always reference the AI generated work and you should never use it as it is generated by an AI tool without changing anything. If you decide to use it without changing anything, then this might be considered violation of academic integrity. You should try to find sources to validate the output an AI gives you. If not, then you might have incomplete or incorrect content in your work. You should edit, proofread and make the text your own.

All reproduced images, photographs, tables and figures in your work must be cited three times: in the text, in the caption beneath the image (including a copyright statement) and in the reference list. You do not have to include a copyright statement if you bought a stock photo or if the image is your own work. In that case, use the words “own work” in the caption or add a note in your text stating that unreferenced photos or drawings are your own.   

Copyright statement example  

Include the following information in the image caption:

Figure X   
Title of the figure   
“From” or “Adapted from” (this is the start of the copyright statement)   
The title, author(s), year of publication, and the source of your image   
Copyright year and the name of the copyright holder   
Copyright permission: “Reprinted [or Adapted] with permission” (only if you have permission) or “In the public domain”.

How to cite when you create new work

If you use other sources, you should always cite them properly, even if they are your own works. Failing to cite your sources properly will ultimately lead to accusations of plagiarism. For an example of how to cite a data set, check out TUlib’s APA citation example (choose Internet/Social media and then Data set). For CC licensed works, you can use the attribution builder to create a proper attribution.   

 Plagiarism   

 Plagiarism is generally a copyright infringement caused by a failure to correctly reference the source when quoting a published work or parts thereof. You must always reference your source. We advise you to use open datasets published in data repositories (e.g. 4TU.ResearchData) and giving credits to the original creator.

The first thing to do is check whether the image, photo, video (still) etc. you want to reuse in your own work is a copyrighted work or a work with an open license (e.g., Creative Commons license). If you cannot find any mention of copyright, you should always assume that it is a copyrighted work (all rights are reserved), which means that you have to ask permission.   

Copyrighted multimedia  

If you want to reuse copyrighted images, photos, video (stills) etc. you need permission from the copyright holder(s) in writing. You must inform the copyright holder(s) about why you need to reuse the image, photo, video (stills) etc., under what conditions and in what environment. For an example of how to request permission, see the request permission form. This is a template only and should be adjusted based on your specific situation.  

If you don’t want to ask permission to use an image, you are allowed to use the right to quote. The right to quote is laid down in Article 15a of the Dutch Copyright Act. This right not only applies to parts of texts, but also lets you reproduce photos and images in their entirety as scientific illustrations.  

There are certain rules to follow when using the right to quote. One important rule is that you must reference the source and the name of the creator. You may only quote works that have already been lawfully published. To quote unpublished work, you need the permission of the creator. A quotation should serve to clarify an argument or description, must therefore be relevant to the argument, and should only constitute a small part of your work as a whole.  

Summarising,  
you have to meet the following requirements when quoting someone else’s work:  

You can only do so for a clearly identifiable purpose.
You may not quote more than is strictly necessary.
You must reference the source.
The source must have been lawfully published.

  If one of these requirements is NOT met, you must ask for permission. You can only use the right to quote when strictly necessary.

Beware:  

Some professionals, such as photographers, cartoonists, draughtsmen, filmmakers, graphic designers, and illustrators are very sensitive about the reuse of their work. After all, it is how they make their living. Generally, limit using the works of these professionals as much as possible.  
The right to quote does not cover using images for decorative purposes in your work (e.g., cover of a paper/thesis). In this case, always ask for permission or use open images.

Multimedia with an open license  

Images, pictures, videos etc. with Creative Commons licenses.     
Images, graphs, charts and diagrams, videos you made yourself and for which you still hold the copyright.
Images, pictures etc. whose copyrights have expired. Generally, copyrights expire 70 years after the year of the death of the creator, after which you no longer need permission to use the image.

For open materials, go to the Open Educational Resources webpage (click on the Open multimedia-tab in the middle of the webpage).

Copyrighted texts

Generally, you need to ask for permission in order to use someone else’s work. In case of multiple copyright holders, permission needs to be taken from all of them. For more information, please check “cite work in” option. You are always allowed to summarize and paraphrase texts written by someone else or you can rely on the right to quote (for more information, see below). You should always cite your sources properly, even if they are your own works. Failing to cite your sources properly will ultimately lead to accusations of plagiarism. The right to quote is laid down in Article 15a of the Dutch Copyright Act. This right does not only apply to parts of texts, but also permits you to reproduce photos and images in their entirety as scientific illustrations. There are certain rules to follow when using the right to quote. One important rule is that you must reference the source and the name of the creator. You may only quote works that have already been lawfully published. To quote unpublished work, you need the permission of the creator. A quotation should serve to clarify an argument or description, must therefore be relevant to the argument, and should only constitute a small part of your work as a whole.

Summarizing, you have to meet the following requirements when quoting someone else’s work:

You may not quote more than is strictly necessary.
You must reference the source.
The source must have been lawfully published.

If one of these requirements is NOT met, you must ask for permission. You can only use the right to quote when strictly necessary.

TIP
If you are using someone else’s work, always check how the owner of the work wants their own work to be used. If you want to re-use work posted on a website or in any other environment, check the terms of use/legal terms/copyright notice of the place where you found the work. If you want to check the open access publishers’ policies, please use Sherpa Romeo to find what they do and/or do not allow.  

Please find below a video where is explained how to use Sherpa Romeo. 

Re-use of your own work

It may be the case that your dissertation, master’s thesis or bachelor’s thesis contains passages that are highly similar to texts found in a manuscript that you write and submit as an article or for a conference proceeding. In such instances, the publisher can consider the submitted work to be ‘plagiarism’ because texts are quoted that have not been referenced. However, TU Delft considers such texts to be unpublished work because they constitute part of a work that has no official publication status.

You can send the editor of the publisher a letter that explains TU Delft’s standpoint. The copyright team can also mediate for you. If the editor still refuses to accept your work, we can place the original texts in your thesis or dissertation under embargo. This means that your thesis/dissertation will no longer be indexed. Your work can then be considered original and the publisher can accept it.

Text generated by AI tools (such as ChatGPT)

Describe how you used the tool in your methodology section or introduction and mention the prompt you used when citing a ChatGPT response.

For more information about how to cite, choose the option “cite works in”.

Texts with open license

To find out what you can do with the text, check the Creative Commons (CC) license. You are always allowed to summarise, paraphrase and quote texts, but do not forget to attribute the source. Failing to cite your sources properly will ultimately lead to accusations of plagiarism. For more information about how to cite, choose the option “cite works in”, article, scientific poster, conference paper, book, dissertation or multimedia.

Texts used under the “text and data mining” exception

If applicable, the researchers can apply the “text and data mining” exception in their research. This can only happen when the purpose is only scientific and the access to the text(s) is lawful. It is not allowed to publish the text(s) obtained based on the text and data mining exception. In case you would like to re-use part of the text(s) in your publication, please check above whether the right to quote could be of help or try to paraphrase or summarise the text(s), otherwise permission is needed.

The first thing to do is check whether the dataset you want to reuse in your own work is a copyrighted dataset or a dataset with an open license. If you cannot find any mention of copyright, you should always assume that it is a copyrighted dataset (all rights are reserved), which means that you will have to ask permission from the copyright holder.  

On this page we refer to the data as datasets which are numerical facts that are organized in a systematic way. If by using the term data you mean that data are e.g., images or works that are protected by copyright separately, you will need to check if you can use these works based on the copyright rules and conditions that apply to each one of these works separately. If in doubt, please contact the Copyright Information Point.

Attention: Not all data can be re-used. Types of data that cannot be re-used are confidential data, personal data or data that are not allowed to be re-used based on a contract or an agreement. Always check what you can or cannot do when it comes to the re-usability of the data. For example, in the case of confidential data, you should check the contract you have signed with the party that gave you access to this data (most likely you will not be able to re-use confidential data as it has “confidential” status). In case of personal data please check the Privacy for Researchers page on the TU Delft website to find out what you can and/or cannot do.

Copyrighted datasets  

If you want to reuse a copyrighted dataset you need permission from the copyright holder(s) in writing. You must inform the copyright holder about why you need to reuse (parts of) the dataset, under what conditions and in what environment it will be used. For an example of how to request permission, see the request permission form. This is a template only and should be adjusted based on your specific situation.  

If applicable, the “right to quote” could also be used within its own limitations. You have to meet the following requirements when quoting someone else’s work (e.g., dataset):

You can only do so for a clearly identifiable purpose.
You may not quote more than is strictly necessary.
You must reference the source.
The source must have been lawfully published.

If one of these requirements is NOT met, you must ask for permission. You can only use the right to quote when strictly necessary.

Datasets with an open license  

Open datasets are datasets with an open license (e.g., Creative Commons license). These datasets are published in data repositories (e.g. 4TU.ResearchData) and can be re-used according to the license conditions. You should always cite your sources properly, even if they are your own works. Failing to cite your sources properly will ultimately lead to accusations of plagiarism. For more information about how to cite, choose the option “cite works”, data.

Plagiarism check on articles, literary works

On request, TU Delft Library creates Plagiarism Similarity reports of articles/papers for TU Delft teachers and researchers using the online tool iThenticate. Only articles/papers that are ready to be submitted to a journal of an official publisher or a conference organizer are eligible to create a Plagiarism Similarity report. Individual papers and chapters not created for this purpose are not eligible for report creation. In principle articles/papers can only be submitted once for a plagiarism check. Use the TOPdesk form to have a Plagiarism Similarity report made by the library. 

Your work regarded as plagiarism? 

 Your work plagiarised?

If you believe your work has been plagiarised by another author/ other authors, please contact the copyright team. Using iThenticate, they will draw up a report that you can send to the publisher of the journal in which the texts plagiarising your work was published. Usually, the offending work will be removed from the publishing platform, or a notice will be placed that the work is suspected of plagiarism.

Signing a contract

We recommend that you carefully review the contract/agreement/statement you are sent by your publisher/third party/website regulator. Try not to give away all your copyrights.

TIP
When you share a work on a website or third-party environment, their terms and conditions apply.

Publishing your work

Usually, publishers request that you transfer your copyright to them, so that they can make commercial use of your work. You can give publishers certain permissions by giving them a license (permission to use) for certain purposes such license to publish, license to communicate the work via their website, etc. If the publisher wants you to transfer the copyright to them, make sure you keep some further use rights (see below). Try to hold on to the right to use your own work in as many ways as possible, thinking carefully about possible situations or ways in which you would like to reuse your own work.

Keep the right to use your work for research and educational purposes. 
Keep the right to use your work within your educational institution and share it with colleagues. 
Keep the right to re-publish it in the TU Delft repository 
Keep the right to use it without asking permission. It is even better to keep the right to use your work for commercial purposes, too. This would include the right to: 
- - use your work on social media (academic social media) to promote it. 
- - republish/reuse your work in future publications, even for commercial purposes. 
- - use your images/graphs/tables, etc. without asking permission for use in educational and non-educational settings and for commercial or non-commercial purposes (if applicable).
- - reuse your work for conferences or seminars.

 Collaborating with colleagues from another university

If you have signed a contract with colleagues from another university, this contract needs to be respected. Check their conditions to see whether you can publish and share your work or not and if yes, under what conditions.

Collaborating with a company

If you are collaborating with a company on your new work, check the conditions for publishing/sharing the work in the signed contract.

Collaborating with students

 Any students participating in creating the work will have the same copyright as you. We recommend making clear agreements in advance. The Addendum Richtsnoer IER sets out guidelines for the relationship between universities and students regarding intellectual property and VSNU industrial rights. For more information, go to the TU Delft Intellectual Property website.

There are different styles for referencing sources properly, such as APA and IEEE. For more examples, please visit the TUlib website and APA 7th Citation Examples.

Choose a license for your own work

Remember that you cannot revoke the license. Once you apply a CC license to your material, anyone is free to use your material under that license for as long as the material is protected by copyright and similar rights, even if you later stop distributing it.

Make sure the material is appropriate for CC licensing and that you have the right to share it under a CC license. For example, confidential information or work created as part of a contract/agreement cannot be shared under a CC license. Specify precisely what it is that you are licensing. Any given work consists of multiple elements, e.g., text, images, music. Make sure to clearly mark or indicate in a notice which of those elements are or are not covered by the license.

Creative Commons provides two options to help you choose the right license.
The first option is a ‘License Chooser’. By answering a few questions, you will receive a snippet of HTML code that the creators of works, their users, and the Web itself can understand. For more information about the licensing possibilities, visit the Creative Commons website.

This table outlines the main license types:

For more information about all types of licenses, please check the general page for Creative Commons.

The second option is to adopt a license by sharing your work on a platform that works with Creative Commons licenses. These platforms have built-in CC options that let you mark your work with a CC license through their account settings. The main benefit of this approach is that it allows other people to find your work when searching for CC-licensed material on those platforms. Platforms that work with CC licenses include Flickr, Vimeo and YouTube.

We recommend using CC BY for your own works to reach a bigger audience and receive more credit.

One of the Creative Commons licenses is essentially a waiver (CC0). We suggest avoiding this license/waiver, as you will give up your copyright and your work will be part of the public domain. This means that anyone could use your work at their own discretion without your permission.

Make sure the license grants permission for what you want to do:

TIP
To find out exactly how to mark your work with a Creative Commons license, go to wiki.creativecommons.org.

If you want to combine or remix two works with a Creative Commons license, check the table below to find out whether you are allowed to. Look for the license of the first work in the first row and the license of the second work in the first column. If the cell where the row & column intersect has a check mark, you can combine or remix the works. Use the most restrictive license of the two for your new work.

How to cite sources in new work

You should always cite your sources properly, even if they are your own works. Failing to cite your sources properly will ultimately lead to accusations of plagiarism.  There are three ways to include information from sources in your own text: you can quote, paraphrase, or summarise it.

Quoting
If the exact wording used in the original document is important, you should quote the text, e.g., when the formulation used by the author matters. Put the quotation between double quotation marks to indicate that the words are not your own and add a reference. Important: long quotations of 40 words or more are considered block quotations and are formatted in an isolated block without quotation marks.

When quoting other texts, bear in mind that:

Too many quotations make your text difficult to read.
Quotations must not be too long. Your text should mostly be your own, not a copy of what someone else wrote.

Paraphrasing

Often, you will find yourself wanting to use ideas put forward in someone else’s work in your own. By paraphrasing other people’s ideas instead of quoting them directly, you can show that you understand the idea(s)in question. A paraphrase is approximately the same length as the original text.
Paraphrase a text by describing the original idea(s) in your own words and adding a reference.

When you paraphrase:

Use your own words. You have to do more than just replace one or two words with a synonym!
Make sure your readers are absolutely clear about which parts of your text are paraphrases, and which parts are your own ideas.

Summarising

Summarising means describing a significant part of someone else’s work in a few sentences. This lets you incorporate a complete overview of someone else’s ideas into your own work. The rules for summarising are the same as for paraphrasing: use your own words and add a reference.

Formatting your references

Text generated by AI tools (such as ChatGPT)

Describe how you used the tool in your methodology section or introduction and mention the prompt you used when citing a ChatGPT response. If the tool allows you to create a link to the output, include this link in the reference, otherwise the full transcript of an answer may be included in an appendix or other supplementary material. Consult the APA 7th Citation Examples (Software > AI Tools) for formatting your reference.

Images

Copyright statement example

The first thing to do is check whether the image, photo, video (still) etc. you want to reuse in your own work is a copyrighted work or a work with an open license (e.g. Creative Commons license). If you cannot find any mention of copyright, you should always assume that it is a copyrighted work (all rights are reserved), which means that you have to ask permission.

Copyrighted multimedia

If you want to reuse copyrighted images, photos, video (stills) etc. you need permission from the copyright holder in writing. You must inform the copyright holder about why you need to reuse the image, photo, video (stills) etc., under what conditions and in what environment. For an example of how to request permission, use the request permission form. This is a template only and should be adjusted based on your specific situation.

If you don’t want to ask permission to use an image, you are allowed to use the right to quote. The right to quote is laid down in Article 15a of the Dutch Copyright Act. This right not only applies to parts of texts, but also lets you reproduce photos and images in their entirety as scientific illustrations.

There are certain rules to follow when using the right to quote. One important rule is that you must reference the source and the name of the creator. You may only quote works that have already been lawfully published. To quote unpublished work, you need the permission of the creator. A quotation should serve to clarify an argument or description, must therefore be relevant to the argument, and should only constitute a small part of your work as a whole. Summarising, you have to meet the following requirements when quoting someone else’s work:

You can only do so for a clearly identifiable purpose.
You may not quote more than is strictly necessary.
You must reference the source.
The source must have been lawfully published.

If one of these requirements is NOT met, you must ask for permission. You can only use the right to quote when strictly necessary.

Beware:

Some professionals, such as photographers, cartoonists, draughtsmen, filmmakers, graphic designers, and illustrators are very sensitive about the reuse of their work. After all, it is how they make their living. Generally, limit using the works of these professionals as much as possible.
The right to quote does not cover using images for decorative purposes in your work (e.g., cover of a paper/thesis). In this case, always ask for permission or use open images.

Multimedia with an open license

Images, pictures, videos etc. with Creative Commons licenses.
images, graphs, charts and diagrams, videos you made yourself and for which you still hold the copyright
Images, pictures etc. whose copyrights have expired. Generally, copyrights expire 70 years after the year of the death of the creator, after which you no longer need permission to use the image.

For open materials, go to the Open Educational Resources webpage (click on the Open multimedia-tab in the middle of the webpage).

Example of reproducing an image with an open licence.

Firmenzentrale Kaffee Partner. The fluid outlines conceal the orthogonal grid of the concrete skeleton construction buildings and lend the architecture an impression of dynamics, 2012. By Emanuel Raab licensed under CC BY-SA 3.0.

Always check the Creative Commons license of a picture, image, etc., to see what you are allowed to do with it.

TIPS

Pictures with people
Before reusing pictures with people, you must be sure that no portrait rights apply. If they do, you must have permission from the person depicted to show the photo/multimedia.
Images of works of art
Before re-using these images, bear in mind that works of art such as statues or paintings are protected by copyright. You are not allowed to use pictures of a painting or statue that you took yourself without permission of the artist.
You are free to use pictures that you have taken of a work of art that is permanently located in a public space (e.g., public road, railway station, shopping centre or town hall). For pictures taken by someone else, you need to request permission. It is important that the work is depicted amidst its surroundings.
Museums and schools are not public places, so pictures taken in a museum, or a school cannot be used without permission.

The first thing to do is check what type of license the software you want to reuse has.
If you cannot find any mention of the license or copyright, you should always assume that you are not allowed to reuse the software because all rights are reserved. This means that you must ask permission from the copyright holder.

Copyrighted software

If you want to reuse copyrighted software, you need permission from the copyright holder in writing. You must inform the copyright holder about why you need to reuse (parts of) the software, under what conditions and in what environment. For an example of how to request permission, use the request permission form. This is a template only and should be adjusted based on your specific situation.

Software with an open-source license

Open-source software licenses indicate how software may be used, modified, or distributed and by whom. Check the Turing Way site for software licenses.

For more information about software licenses and questions about re-using software, contact the Copyright Information Point.

You should always cite your sources properly, even if they are your own works. Failing to cite your sources properly will ultimately lead to accusations of plagiarism. For more information about how to cite, change "re-use works" to “cite works” in the search engine above.

Attention: Not all data can be re-used. Types of data that cannot be re-used are confidential data, personal data or data that are not allowed to be re-used based on a contract or an agreement. Always check what you can or cannot do when it comes to the re-usability of the data. For example, in the case of confidential data, you should check the contract you have signed with the party that gave you access to this data (most likely you will not be able to re-use confidential data as it has “confidential” status). In case of personal data please check the Privacy for Students page on the TU Delft website to find out what you can and/or cannot do.

Copyrighted datasets

If you want to reuse a copyrighted dataset you need permission from the copyright holder(s) in writing. You must inform the copyright holder about why you need to reuse (parts of) the dataset, under what conditions and in what environment. For an example of how to request permission, go to the request permission form. This is a template only and should be adjusted based on your specific situation.

If applicable, the “right to quote” could also be used within its own limitations.

You have to meet the following requirements when quoting someone else’s work (e.g., dataset):

You can only do so for a clearly identifiable purpose.
You may not quote more than is strictly necessary.
You must reference the source.
The source must have been lawfully published.

If one of these requirements is NOT met, you must ask for permission. You can only use the right to quote when strictly necessary.

If applicable, the students can apply the “text and data mining” exception in their research. This can only happen when the purpose is only scientific and the access to the data is lawful. It is not allowed to publish the data obtained based on the text and data mining exception. In case you would like to re-use part of the data in your publication, please check above whether the right to quote could be of help, otherwise permission is needed.

Signing a contract

We recommend that you carefully review the contract/agreement/statement you are sent by the publisher/third party/website administrator. Try not to give away all your copyrights.

Collaborating with a company

If you are collaborating with a company on your (new) work, check the conditions for publishing/sharing the work in the contract you signed.

Collaborating with teachers/researchers

Any students participating in creating the work will own the copyright to their own work. We recommend making clear agreements in advance to create clarity as to who will own the copyright to what in the future. The Addendum to the IPR guideline for students sets out guidelines for the relationship between universities and students regarding intellectual property and VSNU industrial rights. For more information, go to the TU Delft Intellectual Property website.

About Copyright Information Point

Teachers, researchers and students at TU Delft all regularly have questions about copyright. What role does copyright play in your own publications, in teaching situations or when reusing other people's publications? The purpose of this website about copyright is to pass on information and serve as an information desk for any questions relating to copyright. The website aims to provide concrete information and demonstrate best copyright practices as used at TU Delft. Special attention will therefore be focused on the relationship between Open Access and copyright. For questions about this page contact the Copyright Information Point.

General copyright information

Copyright is the exclusive right of the author of a specific scientific, artistic or literary work to use, publish, distribute, share and/or duplicate the work. Such work may not be used, published, distributed, shared and/or duplicated without permission of the copyright holder. (Dutch Copyright Act).

It is a common misconception that copyright law does not apply to the internet. Global copyright laws stipulate that creating text, images, software, music or anything else is protected by copyright law subject to certain conditions.

Content could be anything you create, such as an article or a book, a design, photo, drawing or software program, etc. You do not have to do anything to obtain copyright; there is no registration process as with a patent. A copyright notice (©) is therefore unnecessary. However, the work must bear the stamp of the author’s personality and feature a certain degree of authenticity.

Which materials can be used in your courses, articles, papers etc.? Fill in the relevant options below depending on whether you are a teacher, researcher or student, in order to see what you can or cannot use/do.

You can contact the Copyright Information Point team for assistance regarding copyright questions/concerns/feedback.

It is important to note that copyright consists of two categories of rights, economic and moral rights. On the one hand, economic rights are related to financial reward for the exploitation of the work such as reproduction, communication to the public and distribution. On the other hand, moral rights are related to the personal connection that exists between the author and their work (right to be credited etc.).

The main rule as to the identity of the copyright holder is that the individual or collective who created the work is the copyright holder (first owner of copyright). If the individual or collective created the work as part of their employment, then their employer is usually the first owner of copyright. Moreover, if the individual or collective who created the work has transferred the copyright through a contract, e.g. to a publisher, then the publisher becomes the copyright holder based on the signed contract/agreement.

Furthermore, there might be a case where there is no copyright holder as the work might belong to the public domain. This term means that the copyright has expired or been waived, and the work can be used by everyone. There is no copyright ownership. Copyright expires 70 years after the author’s year of death. This is the general rule, although there are exceptions.

Having said that, it is understandable that if the copyright (economic rights) was assigned to another person/company, or the author created their work under supervision or within a contract agreement, then the assignee/supervisor/company possess the economic rights (they are the copyright holders). You should always check what is stated in the contract before signing it. That’s why it is good to know who creates the copyright and who owns the copyright, so you know how to exploit the work.

Copyright to educational material made by a TU Delft teacher, rests with TU Delft. Amongst the other moral rights, the teacher retains the right to be named.
Copyright on an article, book (chapter), conference paper etc., rests with the author until the moment the copyright is transferred to a publisher, in case it will be transferred.
Copyright on bachelor's and master's theses or any other student work written during the period of study at TU Delft is the property of the student, unless written agreements have been made.

TIP: Please contact us if you have doubts about whether the copyright clause in your contract states that you are the owner of the copyright. We will be happy to assist you.

Creative Commons (CC) is a non-profit organization that enables the sharing and use of creativity and knowledge through free, legal tools. Creative Commons licenses are not an alternative to copyright. They work alongside copyright and enable you to modify your copyright terms to best suit your needs.

Types of Licenses

Creative Commons License

The licenses on the right and their descriptions come from the Creative Commons – About the Licenses page. The following describes each of the six main licenses offered when you choose to publish your work with a Creative Commons license.

(Click to enlarge)

This figure on the right is representing the CC license types from 'Most open' (top) to 'Least open' (bottom).

Creative Commons licenses by Voter CC BY-SA

Public domain (CC0 or PD)

In the figures above, you also see a CC0 logo. This is not a Creative Commons license, but it can be used if a creator wants to waive all his rights. It is a waiver. Their work will be part of the public domain (PD). Public domain is a term used for works that are no longer under copyright. Most works go into the public domain 70 years after the year of the death of the creator.

Choosing a license

Choosing a license for your own work

When choosing a license: for your own work

Remember the license may not be revoked. Once you apply a CC license to your material, anyone who receives it may rely on that license for as long as the material is protected by copyright and similar rights, even if you later stop distributing it.

Make sure the material is appropriate for CC licensing. Specify precisely what it is you are licensing. Any given work has multiple elements, e.g. text, images, music.
Make sure to clearly mark or indicate in a notice which of those are or are not covered by the license.
If you wish to combine or remix two works with a Creative Commons license, you can use the table below to find out if it is possible to do so. Find the license of the first work on the first row and the license of the second work on the first column. You can combine or remix the works only if there is a check mark in the cell where the row and column intersect. For your new work, you must use the most restrictive license of the two.

Example

Learn how to mark work with a Creative Commons license at wiki.creativecommons.org.
Make sure the license grants permission for what you want to do, see flowchart how to choose a license.
We recommend using CC BY for your own documents based on TU Delft’s OER Policy.

Attributing works

Reuse of documents or multimedia

When you are going to use documents or multimedia with a Creative Commons license, you have to attribute them properly.

The following information must be included for a proper attribution:

Title of the work
The name of the creator of the work
The URL where the work is hosted
The type of license under which the work is available and a link to the details of the license

A good rule of thumb is to use the acronym TASL, which stands for Title, Author, Source, License.

Container ship by Frans Berkelaar / CC BY 4.0

Sometimes you might want to use an image from Wikipedia. "Photo by Wikipedia" is not the correct attribution because:

Title: Title is not noted.
Author/Creator: Wikipedia is not the creator of the photo.
Source: No link to the original photo.
License: There is no mention of the license, much less a link to the license. "Creative Commons" is an organization.

Photo by Wikipedia

For examples of other works (e.g. books, webpages, blogs) go to the website of New Media Rights for "best practices creative commons attributions".
For making a good attribution go to: Open Attribution Builder.

Derivative work

When you want to modify an image and add your own details, such as text or shapes, the image will become a derivative work. This is a good attribution for material from which you created a derivative work. “Welcome to the campus” by TU Delft / CC BY 4.0. A derivative work of “Delft Applied Sciences Department” by Przemyslaw / CC BY 3.0.

Material from multiple sources

When you want to modify an image and add your own details, such as a shape and an image found on the internet, the image will become a derivative work. Here you see a good attribution for material from which you created a derivative work.
