Other Reference Managers

EndNote X9 is a software that:

  • stores and organizes references found from many sources
  • inserts these references into a Word document 
  • automatically formats your references according to a predefined citation style, and more! 

If you're new to EndNote, check out the Installation Instructions and Step by Step Guide.

Mendeley is a citation management tool that, like many others, lets you collect & organize citations, & then easily insert them into documents & format bibliographies.  But it also lets you drag & drop PDFs into your library & extracts the metadata to create a library!

You can highlight and annotate your PDFs and share them with others.  Colleagues can then also annotate the same document, with each author displaying as a different color.

Use more than one computer?  It's not a problem!  Download Mendeley Desktop to as many computers as you want, then sync them with a click of your mouse.  Need to use your library away from your computer?  Mendeley Web gives you access to your citations no matter where you are.

Mendeley is social:  create a profile, follow other researchers, create a network of people doing similar research.  Discover the articles and journals that are being read in your field right now.

Create collections of papers.  Make them public & share them with an RSS feed (great for class reading lists!).

What is Zotero?


Zotero is a free bibliographic citation management software that allows you to save, collect, manage, cite, and share research sources. Zotero is available either as a Firefox extension or as standalone software that works with Firefox, Chrome and Safari browsers. It works right in your browser, making it easy to save you citations while you search.
