The Octagon Library is an independent documentary publishing project dedicated to preserving influential texts outside the canonical tradition. The catalogue includes modern study editions of the Book of Enoch, the Book of Jubilees, the Book of Jasher, and the Kolbrin Bible, together with classical philosophy, historical documents, and rare intellectual source texts. The Octagon Library focuses especially on apocryphal literature, Old Testament pseudepigrapha, and non-canonical biblical writings presented in accessible documentary editions for study, reference, and preservation. Alongside early Jewish apocalyptic texts, the collection includes Stoic philosophy, Renaissance political thought, esoteric traditions, and modern documentary works exploring memory, authority, and historical continuity across civilizations. The catalogue forms part of an ongoing archival series restoring alternative scriptural traditions and foundational historical documents to circulation.
