I'll probably do a review of it here, but I just got finished reading a book about the "genre wars", where SF was split off from fantasy, which was then split off from adventure. Essentially, there was a very small group (~50-200) people who ran the conventions, the fanzines, everything that "ran" the publishing industry for SF/F from ~1930-~1965. They ran the industry into the ground, and then mooched off of people (Bradbury, Heinlein, etc.) who were outside the clique, but were actually selling.
