The research contained below is focused specifically on Twitter and other microblogging phenomena. This list is not methodologically or disciplinarily organized. There is work here from communications, information science, anthropology, sociology, economics, political science, cultural studies, computer science, etc. (There is some overlap between this listing and the listing of Research on Social Network Sites.)
I try to keep this up to date so please send me additional publications as you learn of them. I do not host articles so only those hosted elsewhere are linked. Please contact the author if you want a copy of an article that is not linked.
