Mystic Tomes of Ancient Lore
Collectively, our group owns many books related to D&D, most of which we'd be happy to share.
- The Player's Handbook.  
 The entirely indispensable guide to everything you'll need to know to
play D&D.
- The Dungeon Master's Guide.  
 Not very exciting unless you're interested in DM'ing, but if you
are, this is what you want to read.
- The Monstrous Manual.  
 Much like the Dungeon Master's Guide, not normally of any great use
to casual players, but an interesting read nonetheless.
- The Complete Books of: 
- Dwarves
- Humanoids
- Psionicists
 
- Coming Soon:
- Thieves' Handbook
- Complete Book of Ninjas
 
Also, Ben has the Complete Book of Villains, but he guards it like the secret to cold fusion, so I 
wouldn't count on getting your mitts near that one.
