Citing Sources

Why cite your sources

Citing sources is important because it communicates to your audience that you speak authoritatively about what you are talking about.  It also helps your audience contextualize your discussion within the larger academic discussion. 

What and when to cite

When writing, you should cite anything that was not an original idea.  Whether you are directly quoting another author or paraphrasing a larger section of an author's work, you should be citing this material.  You should cite to the extent that you make use of another work.

So many options!   How should I choose?

Typically the choice of style depends on the subject you are writing about and the publication you are submitting to.  In this case your professor will likely choose the style.  If you have a choice of style then it is important to apply that style consistently.
