The Omnidoxical Register is a post-disquisitional segment of the Omnidoxy within the Appendix of the Omnidoxy as part of the Original Omnidoxical Series. It provides an extensive list of disciplines of study categorised within the twelve inclusive disciplines that are given definitions and clearly organised. The Omnidoxical Register acts as an important categoriser for the Astronist tradition of philosophy and continues to be a consistently utilised reference book.
