Citation Managers

Is there software to help manage my citations?

Yes! EndNote and RefWorks are licensed for use by current NU faculty, staff, and students. The open source product Zotero and the free version of Mendeley are two other options that the library supports. Any of these programs can help you collect and manage your references, and auto-format citations and bibliographies in your papers. (Choose just one; they are not meant to be used at the same time.)

For more details on each program, see the introductory pages for EndNote, RefWorksZoteroMendeley or BibTeX.
