The Encyclopedia Magica was a Four book set that lists details of every magical item that various TSR publications has listed over the years.
Most collectors I know have had at least one set at one time or another.
I remember when they could be had for around $20 for the set of four.
I do not own a set now, but if I saw a listing with real nice copies for a low price I would probably go ahead and bite that bullet again.
I would like to read them again.

There was another three book set for Priests as well.

The Trail Maps are a series of Four HUGE Maps (TM1-TM4) showing the world of the Forgotten Realms setting.
They were folded much like you would see a city/street map folded these days.
Stored in a handy folder.
The two more common maps (City of Waterdeep and Kara Tur) sell for around $15-$20 pretty often.
(I just sold a City Map with a BIN for $14.95)
The Eastern and Western Counties Maps tend to sell for more individually.

A couple additions/corrections:

Encyclopedia Magica - 4 books listing all the magic items
Wizard's Spell Compendium - 4 books listing all the wizard spells
Priest's Spell Compendium - 4 books listing all the priest spells

These are second edition products, but list everything from O, BECMI, 1e, and 2e era (up to the time of publication, of course).
I think these are actually pretty cool, though they sometimes sell for more than I think they're worth.
