Liber Extra
The term was first applied to those papal documents which Gratian had not inserted in his "Decree" (about 1140), but yet were obligatory upon the whole Church, also to other decretals of a later date, and possessed of the same authority. Bernardus Papiensis designated under the name of "Breviarium Extravagantium" or Digest of the "Extravagantes", the collection of papal documents which he compiled between 1187 and 1191. Even the Decretals of Gregory IX (published 1234) were long known as the "Liber" or "Collectio Extra", i.e. the collection of the canonical laws not contained in the "Decree" of Gratian.
