The Wizard’s Spell Compendium (Vol 1 - 1996, Vol 2 - 1997, Vol 3 and 4 - 1998) and the Priest’s Spell Compendium (which I do not own) is a project similar to the Encyclopedia Magica (though, in my estimation, a slightly less exciting one). It collects every magic-user spell from 1975 to 1995 (though at least some spells published in 1996 products made their way in) but omits some systems that stray too far from the game’s core Jack Vance-inspired magic (spellfire magic, for instance, and the psionic-laced magic of Dark Sun’s dragon kings). Many of the spells were updated for consistency, which is nice, and there are references to the original source for archival purposes. The spells are listed alphabetically with little icons to indicate if they are from a specific campaign setting.
It’s a pretty massive, exhaustive and slightly exhausting project. I appreciate that the books exist (if for no other reason than for the fun selection of art by Ken Frank, Arnie Swekel and Glen Angus). As an aid for play, though, I find these a good deal less useful than the magic item books. Management of spells is one of the most tedious tasks in D&D in my humble opinion and a gigantic heap of all the spells ever is…not as helpful in practice as they might seem.
