(Did you mean a fanzine by John Nielsen Hall?)
It typically means fanzine, but has been known to apply to the proz or mundane amateur magazines. The term herein will always apply to publications that come from the sf microcosm or one of its off-shoots.
The word spread into mundania as a term for self-published magazines, once called "little magazines," that came out of the Factsheet Five phenomenon. The difference between a fanzine and one of these may not be easily distinguishable, given that our fanzines don't need to be about sf or fandom, but has to do with the publisher's sense of being part of fandom.
