Many moons ago I picked up the large and voluminous Atlas of Krynn, back when RPG stuff was still sold in bookshops, and was delighted with the detailed collection of maps, diagrams, city plans, and more contained within. Just on a random impulse I decided to google it this morning, and here's the whole thing on Scribd (http://www.scribd.com/doc/34101930/Dragon-Lance-Atlas-of-Krynn), under an attribution non-commercial licence. If anyone is interested, there's lots of good stuff in there.
So are there any other such resources floating around, ye olde almanacs and atlases that might have passed into the common if not quite public domain?
Another thread just reminded me, the collected World of Lone Wolf gamebooks are all freely available here (http://www.projectaon.org/en/Main/Books), with maps, monsters, adventures, magical items, the works.
