Encyclopedia Magica Volume Three: Pick of Earth Parting to Thesis on Conditional Ruptures (Spellbook)
From the Introduction to Volume One:
Throughout the 20-year history of the D&D and AD&D game worlds, reams of paper and gallons of ink have detailed thousands of magical items. From the original Dungeons & Dragons (Woodgrain Box & White Box Sets) and the first issue of The Strategic Review Magazine, to the last products shipped in December 1993, almost every product has featured at least one new magical item, and you will find them all in the Encyclopedia Magica collection. Since many of these products are long out of print, it is impossible for the majority of players and Dungeon Masters around the world to enjoy these unique treasures. We had to call a halt at some point, so these volumes only include those products shipped through December 1993.
From the credits at the front of the book:
Design: It is impossible to list all of the creators of the items catalogued in these volumes, but credit goes to everyone who has created a magic item in a module, boxed set, accessory, hardbound, or magazine article published in the last 20 years.
