Citation management software helps you:
This guide only covers citation software supported by U-M Library: Zotero, Mendeley, and EndNote. When deciding which one to use, consider your research habits, word processing needs, and collaboration/sharing needs. These programs can work with each other and some people may need to use more than one throughout their academic career.
Zotero has a citation style that meets NSF's proposal requirements. It isn't available by default in Zotero but you can add it. Directions on how to add or import new citation styles into Zotero can be found here. You can search the Zotero Style Repository to see the over 8,000 citation styles available.
