Looking good
But was do the abbreviations DRW, Sp, D, etc. mean? Oops, I think I may have guessed a few - D = Drow of the Underdark, M = Menzoberranzan, Sp = Spellbound...
Actually, one thing you might want to consider is that sometimes, a later supplement replaces an earlier supplement; for example, a lot of the priestly spells (granted by drow deities, for example) were reprinted in later sources (like Demihuman Deities), and often editted in the process... It can get messy
Yes, working on it can be monotonous, but it is the thrill we get when these things are done that drives us on!
(Art is very similar...)
