Ideas and information that are unpublished such as a student paper or presentation don't need to be cited.

a. True

b. False

This is false!

Whenever you use a source in your work, or an idea that is not yours, you should cite it. This applies to unpublished work, too.

Think about like this - in this case no one can ever accuse you of plagiarism - after all you were open about the source in the first place!
