Back when I was publishing a single-sheet newsletter for meetings of the Penn State Science Fiction Society (the arrogantly-named Dangerous Advice, I often went to the FANAC archives for filler material. They have a largeish fanzine archive, as well as a number of interesting fan histories scattered hither and yon in the somewhat-convoluted site design.
I went through something of a mania for fan history in the late Nineties. I find that I've lost that enthusiasm. Perhaps because it's mostly old news to me now? Possibly I'm not as big of a fan as I used to be.
