Mendeley allows users to collect, organize and annotate research articles and other document types individually and in shared group libraries.
Mendeley was created by three Ph.D students in 2007.
It has been owned and operated by Elsevier since 2013, and works well with other Elsevier products including ScienceDirect and Scopus.
The Mendeley Reference Manager (RM) serves as Mendeley's downloadable library organization and annotation tool, replacing Mendeley Desktop.
The Mendeley Web Importer connects to your browser to make it easier to import items into your library from the websites and databases in which you find them.
Mendeley Cite is the citation plug-in for Microsoft Word. Download through Mendeley Reference Manager or Desktop (Tools tab) to make sure it's the right one for your version of Word, or find the Office Online/Office 365 plug-in on the Microsoft App store.
The basic storage plan (2GB) is free and includes the ability to create and support up to 5 shared group libraries of up to 25 users (100MB shared storage across all groups).
More storage is available through "Premium Packages" for a fee:
Styles can be downloaded within Mendeley Desktop by going to Citation Styles under the View tab, and then clicking on More Styles.
The screen shown here will let you search for the style you need and install it that way, or download via the source URL from one of the libraries below.
It will then appear in the citation style options when you export your items as a bibliography.
