You have many options when it comes to selecting a program to manage your citations; view the columns below and the tabs above for more information on specific citation managers.
All citation management programs let you:

  • Add citations from databases like PubMed, Web of Science, etc.
  • Organize your citations into folders or groups
  • Add PDF files of articles to the references
  • Format citations in Microsoft Word (and other document programs) to create bibliographies in any of 1000s of styles
  • Share all or part of your database, with various degrees of permissions

Comparison of reference management software (Wikipedia): Comparisons of over 20 desktop-based and web-based tools. Includes information on integration with word processors, supported platforms, import/export capabilities, citation styles, and more.

EndNote is a client-based program, which means the software resides on your computer and is not accessible via the Internet. EndNote features include:

  • Client software installed on your computer (can sync with a limited web-based version)
  • Linking EndNote records to PDFs and other types of documents saved on your hard drive
  • Can add figures and tables to your EndNote library
  • Use UC-eLinks to find the full text of the article from within EndNote
  • EndNote software must be purchased and installed onto your computer
  • Can share your EndNote library with others

EndNote KnowledgebaseFAQs, and the Tutorials Library are the best places to start when you are learning EndNote or have problems.

For a comparison of the differences among the current EndNote version and earlier versions, see their comparison chart.
