At this point the official collections stop. The two last, which have
found a place in the editions of the _Corpus_, are collections of
private authority, but in which all the documents are authentic.
Evidently the strict prohibition of the publishing of collections not
approved by the Holy See had been forgotten. The _Extravagantes_ (i.e.
_extra collectiones publicas_) of John XXII. number 20, and are
classified under fourteen titles. The _Extravagantes communes (i.e._
coming from several popes) number 73, from Boniface VIII. to Sixtus IV.
(1484), and are classified in books and titles. These two collections
were included in the edition of Jean Chappuis in 1500; they passed into
the later editions, and are considered as forming part of the _Corpus
juris canonici_. As such, and without receiving any complementary
authority, they have been corrected and re-edited, like the others, by
the _Correctores romani_. They are cited, like the decretals, with a
further indication of the collection to which they belong: _Extrav. Jo.
XXII._, or _inter-comm-(unes)._
