At their most basic, citation management tools help you collect citations for articles, books, webpages (and lots more) to use in your research, and to create bibliographies in your writing using a particular citation style (APA, MLA, Chicago, and many others.) More advanced features in citation management tools allow you to:
Store source materials such as PDFs
Add in-text citations and bibliographies to your assignments and papers
Share the citations you've collected with others
What Tool Should I Use?
UA Libraries provides limited help and support for these three citation managers:
Mendeley and Zotero are free. EndNote is free to UA students, faculty, and staff through a campus site license.
Consider setting up an account for one of the tools and try it! Once you choose a tool, you can always change your mind; citations can be transferred between tools. (Attachments like PDFs don't always transfer.)
