There are a couple spread out in some of the newer books. Has anyone ever compiled them? Does anyone know which books they appear in?

Races of Eberron has spells that give you small bonuses as long as you have them prepared.

There's a solid pile in Dragon Magic. I'd rather not make a list, so just check out the magic section thereabouts.
