The Chronicle of Higher Education posted an article on April 29, 2012 titled “Social Networks for Academics Proliferate, Despite Some Doubts“. The social networks mentioned are:
Academia.edu, “The profile … includes far more information than a university’s Web page could accommodate, including links to research papers, books, blogs, and forthcoming talks. It lets people know what he’s working on and helps him connect with others in his field.”
Mendeley.com, “is a program for managing and sharing research papers that includes both a desktop application and a social-networking site.”
ResearchGate.net, “allows scholars to share research papers.”
Zotero.org, “offers similar technical tools for researchers in other disciplines, including many in the humanities. The free system helps researchers collect, organize, share, and cite research sources.”
FacultyRow.com “provides online forums so scholars can link up through text or video chats.”
