Several versions of reference management software are listed below. Some have free basic versions, some require payment to use, and some are completely free.
- EndNote- EndNote is a reference management software that allows you to search databases for citations, import citations, store and organize your citations, create bibliographies and share with up to 14 others (all users must pay for the software). There is a free, basic version of EndNote available that has limited storage and does not allow sharing files with colleagues.
- RefWorks - a reference management software that is designed to help researchers gather, manage, store and share all types of information, as well as generate citations and bibliographies. All users must pay for access to the software. There does not appear to be a free version of this software.
