Fanac

Fanac is a fan slang term (constructed from FANnish ACtivities) for activities within the realm of science fiction fandom. It has also been used as a title for at least two science fiction fanzines, one published by Terry Carr and Ron Ellik, and later continued by Walter H. Breen, in the late 1950s through early 1960s; and the other published by Swedish fan John-Henri Holmberg from 1963 to 1994.
