0-933635-70-2. This is part of an excellent role playing game, but the
books are worth reading by themselves as well. There are several books
the game is made of, purchaseable separately. Most of it is a very
detailed glossary of people in the various versions of the saga (with
primacy to Mallory's), but almost half of it is spent on similar
glossaries of notable places, of special "things", and many other
fascinating tidbits, such as an attempt at a self-consistent
chronology of Arthur's reign, and so on.
