This is a catalog/index page from a digital archive (sacred-texts.com) listing primary texts of Thelema, the religious-philosophical system founded by occultist Aleister Crowley in the early 20th century. The page inventories roughly 100 Thelemic documents, primarily Crowley's own writings under the "Liber" naming convention, along with works by associated figures such as Jack Parsons, Frater Achad, and H.P. Blavatsky (with Crowley commentary). The texts span practical magical instruction (rituals, invocations, initiation ceremonies), mystical doctrine (the Holy Guardian Angel, grades of initiation within the A∴A∴ and OTO orders), sexual magick, Qabalistic study, and philosophical commentary drawing on Taoism, Buddhism, and Hermeticism. A distinctive organizational feature is the OTO's "Class" system (A through E) indicating each document's relative doctrinal importance. The page also notes a copyright dispute: the OTO claims rights over many documents that are arguably public domain, though the archive has kept them available for non-commercial use.
