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 80–100 titled works (called "Libri," Latin for books) produced by Crowley and associates in the A∴A∴ and OTO initiatory orders, covering ritual magic, mysticism, sexual magick, Qabalah, yoga, and Thelemic law. Each entry gives a number, an OTO classification of importance, and a brief description of the text's purpose—ranging from practical instruction manuals (breath control, astral projection, banishing rituals) to doctrinal expositions and magical diaries. A distinctive feature is the breadth of synthesis on display: Crowley drew on Western esotericism, Eastern traditions (Taoism, Buddhism, yoga), Enochian magic, and his own channeled scripture (The Book of the Law) to construct a unified initiatory system. The page is a navigational gateway, not an analytical work—its value is as a structured bibliography for researchers or practitioners trying to locate specific Thelemic source material, with brief annotations that distinguish devotional, instructional, and theoretical texts.
