I put together some spell reference booklets for the cleric and magic-user. The source material is the Labyrinth Lord Advanced Edition Companion, but I pulled out the IP and also fixed the spell entries that say things like "this is the same as the cleric spell, so go look up that one even though you are a magic-user".
The PDFs are interior pages only, so you will have to make your own covers for these booklets using your favorite copyrighted art. I would have included the one I made for myself, but the art I used is from a currently in-print book that is less than 30 years old, so I figured I'd try not to piss those people off.

P.S. - If I ever get a player that plays a druid or illusionist, I might do those as well, but I don't see that happening in the near future.
