Mendeley is a reference manager program that allows you to manage citations, automatically insert citations into your papers, and connect with other Mendeley users via social networking.
What Makes Mendeley Different?
Mendeley is one part reference management software and one part social network. It has many features that are similar to other reference management programs, but offers some unique benefits:
The references you upload are saved in the cloud so you can access them via Mendeley anywhere you have access to the internet.
You can attach documents, like article pdfs, to Mendeley records. The pdf viewer allows you to mark-up a paper and share your notes with others through Mendeley Groups.
Your citations are added to a crowd-sourced catalogue that contains all of the references saved by all Mendeley users. You can search the catalogue for papers that your colleagues are reading, and get statistics on how often a reference has been saved by the Mendeley community.
