Chris Tichenor compiled an excellent list of all the products released by TSR for Dungeons & Dragons and Advanced Dungeons & Dragons between 1974 and 1988, which I've reproduced below. What I like most about this list is the way it reveals trends in both the kinds of products TSR was publishing and the way that D&D was conceived of by the company. Tomorrow sometime, I'll post my own year-by-year thoughts about this list, but do feel free to make your own comments about it beforehand. I'm curious to see how much intersection there is between my own opinions on this matter and that of my readers.
