Diese Liste enthält die Libri von Thelema, die Bücher des Thelema-Systems (, Plural libri), stellt also eine Art Kanon des von Aleister Crowley begründeten Orden des Astrum Argenteum (A∴A∴), des Ordo Templi Orientis (O.T.O.) und allgemein der Nachfolger Crowleys und der Thelema-Tradition dar.

Die meisten Texte gehen auf Aleister Crowley zurück. Wenn nicht anders vermerkt, kann von einer Autorschaft Crowleys ausgegangen werden. Viele der kürzeren Schriften erschienen in der Zeitschrift Equinox oder auch in The International. Ebenso gehen die Inhaltsangaben weitgehend auf Crowleys A Syllabus of the Official Instructions of the A∴A∴ (Liber 207) zurück.

Die Titel entsprechen häufig dem Muster Liber A vel B sub figura X, was als Buch A oder B mit Nummer X gelesen werden kann, wobei X eine Zahl in römischen Zahlen ist.

Die Länge der der rund 140 Texte ist sehr unterschiedlich. Manche der „Bücher“ umfassen nur einige Absätze, andere haben den Umfang mehrbändiger Werke (zum Beispiel Liber 4).

Klassen Die Klasse der einzelnen Schriften ist eine Klassifizierung des A∴A∴ entsprechend der Bedeutung der jeweiligen Schrift, wobei die wichtigsten Schriften in der Klasse „A“ sind. Einige der Schriften gehören zu mehreren Klassen. Die Klassen A bis D gehen wie die Inhaltsangaben auf Crowleys Liber 207 zurück. Schriften des O.T.O. haben keine Klassifizierung. Die Klassen im EinzelnenSiehe die Einleitung auf der Libri-Seite des O.T.O.
