The Contents of Friedrich Maassen's Geschichte der Quellen und der Literatur des canonischen Rechts im Abendlande (Paris 1870)
(available in PDF format from Google Books, click the above link)

The canons of church councils have come down through the ages in various versions found in many manuscripts.  This work gives the history of the texts of church canons and papal letters from the early church to the Middle Ages.  Maassen does not use all historical sources, but only that which is found in Medieval collections of canon law (e.g., he does not include letters preserved in Athanasius' writings, but he does include letters found in the Collectio Novara) . We have the translated contents only for the first seven parts of Maassen's work.  The first six parts contain canons from church councils; the seventh and longest section contains papal letters, which were often issued from Roman assemblies rather than a set of canons.

The number preceding the council or letter is Maassen's paragraph number, not the page number.
The number in parentheses following the council or letter is the date.
In section seven, we have given the recipient where possible, followed by the incipit.
For the sake of clarity we have assigned letters, rather than numbers, to the papal letters of section seven.
