encyclopedia of 5000 spells is a good one, theres some useless ones in there because the author (judika illes) seems to like her folklore, but theres some really awesome stuff too.
also the crones book of charms and spells by valerie worth.
and for general magic, interestimg facts and nice ways to look at life try the grimoire for the apprentice wizard co written, compiled and edited by oberon zell ravenheart. its a very good book and i still love it after ~five years.
sorry for any typos,im writing via phone and its not very good for typing on
