What pre-3E D&D book are you using most in your 3.X game?

I've been going through my box of older D&D and related gaming stuff. I realized how many of these books are still useful in the age of 3E. Books like the various "sites" books (City Sites, Country Sites, etc.), the Book of Lairs I & II, etc.

Which book (or books) do you find yourself still using?

The Gazetteers, written for basic D&D, get referenced a lot in my D&D3.5/AE hybrid Mystara game. I would say Kingdom of Ierendi would be #1, just because the bulk of the game to date has taken place there. (It's not a case of that being my favorite Gazetteer; I'd say it's actually one of the weakest of that series, though that's a comment on how good the other ones are, not on any problems with KoI.)

Quick, anybody else know a campaign setting that starts with dark? I seem to be on a roll.

Dark Space.
