This is a bibliographic catalog — an annotated index — of sacred and instructional texts associated with Thelema, the occult philosophical system founded by Aleister Crowley in the early twentieth century. The catalog lists roughly 60+ numbered volumes (called "Libers") produced by or associated with Crowley's magical orders, the A∴A∴ (Argenteum Astrum) and the OTO (Ordo Templi Orientis), along with an OTO-assigned "Class" rating indicating each document's relative importance. The works span a wide range of genres — ritual instructions, initiatory manuals, mystical poetry, magical diaries, philosophical essays, and fictional allegories — unified by Thelema's central doctrine that humanity has entered a new spiritual "Aeon of Horus" governed by the law "Do what thou wilt." A notable feature is the catalog's candor about content often treated esoterically elsewhere: several entries are openly labeled as sexual magic (covering practices like IX° OTO sex rites), and descriptions acknowledge that symbolism frequently veils explicit sexual-mystical teachings. The index also includes non-Crowley material Crowley translated or commented upon, such as Taoist classics and Blavatsky's *The Voice of the Silence*, reflecting Thelema's syncretic absorption of Eastern and Western esoteric traditions. It functions primarily as a finding aid for researchers or practitioners deciding which texts to pursue, with brief but substantive descriptions that reveal both the practical-instructional and cosmological scope of the Thelemic corpus.
