This article in the Inland Valley Daily Bulletin profiles library science fiction holdings at the California state school in Riverside. Those holdings include a ton of rare comics -- comics that sound like they're just out there on the shelves -- and box after box of fanzine material donated by superfan Fred Patten, identified in the article as "Frank Patten," which may be more accurate, I don't know. It should be interesting to see what collections of this sort of material develop in the next ten, fifteen years. My hunch is I think there will be a smaller than expected window where libraries will gain a foothold in this area -- it may already be shut.
