Citation Management Software allows you to capture, store, organize, and format citations in a wide variety of citation styles. In addition to the citation information (author, title, publisher, date, etc.) these applications have a variety of features that allow you to work collaboratively, include reading notes, include article full text PDFs, and much more.
EndNote : NU Libraries has a site license to this software which is available to you (along with upgrades) as long as you are enrolled. Desktop and web-based versions of the software are available, and your citation database can be synchronized across both versions.
Zotero : a free bibliographic citation manager. Extensions for Chrome, Safari, and Firefox allow you to easily save citations you find online.
Mendeley : another free bibliographic citation manager.
The guides available at the links above should get you started using any of these software applications. Use my contact information to make an appointment to review how to use these applications.
