Mendeley is a free-web and desk-based reference manager and an academic social network.
Mendeley can help you to organize your research and to collaborate with other researchers. Mendeley has several special features, including syncing between Mendeley desktop and the Mendeley web account; always access from another computer, Iphone of Ipad; importing and organizing PDFs and sharing articles and PDFs with other Mendeley users.
From www.mendeley.com you can install the "Web Importer". The Web Importer is a browser plugin that allows you to select and import references into your Mendeley library while searching in systems like Scopus, Google Scholar, and PLoS.
With its free account Mendeley allows you to create public groups and private groups. In public groups you can exchange references, but not PDFs. You can also create as many public groups as you want. In private groups you can also exchange PDFs, but you may create only one private group for up to three users. If your team needs a larger private group, the library can create a private group up to 15 users. Send your request to Servicedesk.firstname.lastname@example.org. Once the account is created, you can invite users to join, including users from outside WUR.
