Pat said:You're probably talking about Thirty Years of Adventure: A Celebration of Dungeons & Dragons, with a foreward by Vin Diesel. It's still dirt cheap on Amazon, if you want a copy.
These focus more on the history of RPGS in general, but D&D is inexorably meshed with the more general history so they're definitely relevant:
Heroic Worlds: A History and Guide to Roleplaying Games, by Lawrence Shick is probably the best index of pre-1990s RPGs, with some brief histories.
The Complete Guide to Role-Playing Games by Rick Swan is similar but less comprehensive.
The Fantasy Roleplaying Gamer's Bible by Sean Patrick Fannon covers the origins of the hobby, from wargaming on.
A History of Role-Playing by Steve Darlington is another easily accessible source:

Shared Fantasy: Roleplaying Games as Social Worlds by Gary Alan Fine is a sociological study from the 1980s about RPGs, with some history.
The Brief History of Game column, by Shannon Applecline focuses on companies instead of the industry as a whole and is more recent, but has some good research:

No. The first three are lumped together because they overlap, but the rest are fairly different. Heroic Worlds and Shared Fantasy are probably the best, given their limitations (HW is mostly an index, and while SF is a landmark, I've seen some claims that they double-counted some of the people in the study so it's less representative than it implies). Steve Darlington's webpage is probably the the most accessible overall summary, but there is less focus on D&D than you'd think. The author is one of the few who didn't come into the hobby via D&D; there might be something more D&D-specific on the web at Dragonsfoot or the Acaeum or elsewhere, but I haven't seen it. Just straightening out the early editions of oD&D and Gygax versus Arneson is a trick.rossik said:niiice! are they in preference order?
