Biology: Citing Sources

OWL (Purdue) Citation Guide

OWL header

OWL resources will help you learn how to use the American Psychological Association (APA) citation and format style. This section contains resources on in-text citation and the References page, as well as APA sample papers, slide presentations, and the APA classroom poster.

Citation Management Tools

Citation management programs allow you to collect, organize, cite, and share references from articles, books, websites and more.

GVSU students and faculty will have access to RefWorks through 2014, but not after that. We recommend Zotero as an alternative.




Zotero is the only research tool that automatically senses content, allowing you to add it to your personal library with a single click.


Mendeley is a free reference manager and academic social network that can help you organize your research, collaborate with others online, and discover the latest research.

Scientific Citation Style

Some scientific disciplines request variations on Scientific citation style, which can look very different from APA. Use the source below to help format citations in Scientific styles. 


American Psychological Association (APA) Style Guide

News: the 7th ed. will be out in October 2019 and we will update resources as quickly as possible.

Below are online resources for learning and using the Publication Manual of the American Psychological Association, commonly called "the APA style guide." More information can be found in the print version of the manual, available from the GVSU University Libraries:
