Biology Information Literacy Part I: Resources & the Library: Citation Styles

Citation Styles

There are many different citation styles that are used for research papers.  There is no standard citation style for biology, however, in this guide we will focus on the Name-Year style from The Council of Science Editors (CSE).  The CSE style is designed for the general sciences, including biology.

Ask your advisor or professor about the citation style they prefer.  Regardless of the style, apply it consistently throughout your paper and make sure to proofread it the same way you would proofread the rest of your paper.

Here are some guides covering the CSE style:
