The "Bulletin" printed by Mnémo in Canada is all in French, but their archives have articles of interest to folk musicians. In the on-line archives, I noticed:
1996- The fiddling music of Prince Edward Island, Celtic and Acadian tunes in living tradition. 1996- Musiciens traditionelles du Québec, 1920-1993. 1997- Du set au cotilion [dance, with some set figures]. Issues for 2001, etc., have more on dance. 1998- [Articles on dance in Qué'bec] 1998 Au-delà du reel [Introduction to traditional instrumental music of Québec]. 2002- [A review of vol. 1 of Kelly Russell's Collection, The Fiddle Music of Newfoundland and Labrador] And many more-
