The last published overview of social movement studies in Ireland was probably the introduction to Connolly and Hourigan's Social Movements and Ireland a decade ago.
Olivier Fillieule and Guya Accornero (eds.), Social Movement Studies in Europe: the state of the art (New York: Berghahn), just published, has 10 chapters covering research on different kinds of movement and 15 on social movements research in different countries.
A preproof version of Laurence Cox's chapter on social movement studies in Ireland is available online here. The chapter catches up on what has happened in the past decade, as well as covering research in different disciplines and theoretical frameworks and work by independent scholars outside academia.
