This is a catalog/index page from Sacred-Texts.com listing the Thelemic canon — the body of sacred and instructional texts associated with Aleister Crowley's occult philosophy of Thelema, as practiced through his organizations A∴A∴ and the OTO (Ordo Templi Orientis). The page functions as a reference table rather than a continuous argument: it enumerates over 100 numbered *Libri* (books), each identified by Roman numeral, an OTO classification of importance, a short title, and a one-sentence description of its purpose or content. The texts themselves span a wide range of forms — ritual instructions, magical diaries, philosophical essays, poetic allegories, translations of Eastern classics, and sexual magic manuals — organized around Thelema's core doctrine that the present cosmic age (the Aeon of Horus) demands a new law of individual will and spiritual self-realization. A notable feature is the catalog's candor about contested matters: it acknowledges OTO copyright claims on texts that may legally be in the public domain, notes deliberate inaccuracies in some texts, and includes entries on drug use and explicitly sexual magic alongside more orthodox initiatory material. Anyone researching Western esotericism, Crowley's output, or the structure of initiatory magical orders would find this a useful survey of the breadth of Thelemic literature, though the page itself provides descriptions only — not the texts in full.
