This is a reference catalog page from Sacred-Texts.com listing the canonical texts of Thelema, the religious-philosophical system founded by occultist Aleister Crowley in the early 20th century. The catalog enumerates roughly 100 "Libers" (books), each assigned a Roman numeral, an OTO classification grade (A through E indicating importance), and a brief description of its contents — covering ritual magic, mystical attainment, sexual magick, Qabalah, yoga practices, and initiatory grade work within Crowley's A∴A∴ and OTO organizations. The collection spans Crowley's original writings alongside contributions from associates like Jack Parsons and Frater Achad, and includes Crowley's translations/commentaries on external texts such as the Tao Teh Ching and Blavatsky's Voice of the Silence. A distinctive feature is the frank inclusion of texts on sexual magic (labeled as such, sometimes "veiled in symbolism") and a diary documenting cocaine and heroin use, reflecting Thelema's transgressive approach to spiritual practice. The page also notes an ongoing copyright dispute: the OTO claims ownership over many texts that are arguably in the public domain, though Sacred-Texts hosts them for non-commercial use.
