Education: Manage your Citations

Citation Managment Programs

Citation management programs allow you to store references and attachments (up to a storage limit), create references in specific citation formats like APA, generate bibliographies, integrate with Word, and share folders with colleagues.  Popular programs include RefWorks, Mendeley, Zotero, and EndNote.


Desktop - EndNote X9 for students (Win/Mac) can be purchased at a student discounted price of c. $115.95 from the EndNote Online Store

Online - Sign-up at the EndNote site while on campus or proxied into the Library. Once signed up, you can log in from anywhere, but the initial sign-up must be done through the Library.  You may use any of your email addresses during sign up.
