The Libri of Aleister Crowley


Do what thou wilt shall be the whole of the Law.

Aleister Crowley classified his more important works about Thelema in a couple of different ways. He used a system of numbered libri (Books) to set these particular works apart from his other writings, thus we have titles like “Liber II: The Message of the Master Therion”. He also further categorized them according to “Class”. The class designation specifies the nature of the work itself, defining its intended usage, and also lets us know the importance of the book in the grand scheme of the system. An explanation of these classes is as follows:

  • Class A consists of books of which may be changed not so much as the style of a letter; that is, they represent the utterance of an Adept entirely beyond the criticism of even the Visible Head of the Organization.
  • Class B consists of books or essays which are the result of ordinary scholarship, enlightened and earnest.
  • Class C consists of matter which is to be regarded rather as suggestive than anything else.
  • Class D consists of the Official Rituals and Instructions.
  • Class E consists of public announcements and broadsheets.
