When it is time to gather all of your notes and start writing the paper, avoid the most common mistake - plagiarism. Plagiarism is not only taking large parts of someone else's work and not attributing credit to that author; paraphrasing sections of a work, even using synonyms and citing the work, is also plagiarism.
Even if the ideas are rewritten, the source of the idea must be cited and the author given credit.
For further information, see the section on plagiarism in the Gingrich Guide or the material on paraphrasing or plagiarism from the OWL at Purdue.
