You may have noted that I’ve put up the fact in the sidebar that I’m part of the Drive Thru RPG affiliate program. These guys do PDF publishing, which is actually a pretty handy way to get access to roleplaying game material that’s: a, obscure; b, out of print; or c, privately generated. I bought my copy of Ken Hite’s Dubious Shards there (very good combination of analysis of the Cthulhu Mythos, with a Delta Green adventure added in); I’ll probably pick up Tour de Lovecraft if/when I ever get the money together to get away with buying it.
Also, check out e23, which is Steve Jackson Games‘ own electronic publishing store. I don’t see anything from that, but it’s got a lot of good stuff in it anyway.
