This edition of the Lesser Key of Solomon is based on manuscripts from the British Museum, edited by two prominent occultists (mostly Mathers and probably Aleister Crowley). This is a considerably cleaned up and modernized version of the Lesser Key, which is obviously intended to be used as a working document for serious magicians, rather than a rigorous transcription of the source manuscripts. However, the information presented here is linked with the other Goetic grimoires and this version is considered one of the best of this literature. Also available on this site is The Greater Key of Solomon the King.
