Start with books and survey/overview papers: they are generally easier to digest. Then try some more specific journal papers. Use conference papers mainly for finding out about recent results.
Keep track of conferences and journals on your topic and check (once in a while) whether some interesting articles have been published in those.
As soon as you find an interesting article, also check the author's homepage(s) for more recent results, and of course follow the references made in this paper.
Find people in our faculty or another faculty at TU Delft, or otherwise nearby who have more expertise in this field than you have and ask (email?) them to recommend some literature or conferences.
Search on-line using a computer on the campus of your university; many journals are available only to subscribers, and this is often checked using the IP address your browser sends along.
Add a paper to your BibTex database as soon as you find it (before you even save/print it).
Try to focus on one original idea in your paper. Summarize it in the abstract, introduce it in the introduction, explain it in detail in the body, and draw some conclusions in the final section.
