st complete work on the texts up to the 9th
century is F. Maassen, _Geschichte der Quellen und der Literatur des
canonischen Rechts im Abendlande_, vol. i. (all that has yet appeared,
Gratz, 1870). For the period between the False Decretals and Gratian,
there is no work of this sort, but the materials have been put
together and published in part by M.P. Fournier. After Gratian, the
classic work is Schulte, _Geschichte der Quellen und Literatur des
canonischen Rechts von Gratian bis auf die Gegenwart_ (3 vols.,
Stuttgart, 1875 et. seq.). Manuals for the study of the sources: Ph.
Schneider, _Die Lehre von den Kirchenrechtsquellen_ (Regensburg,
1892); F. Laurin, _Introductio in Corpus juris canonici_ (Freiburg,
1889); Tardif, _Histoire des sources du droit canonique_ (Paris,
1887). Most of the German manuals on canon law devote considerable
space to the history of the sources: see Phillips, vol. ii (3rd ed.,
1857; French translation by the abbe Crouzet); Vering, 3rd ed.
(Freiburg, 1893); Schulte, _Das katholische Kirchenrecht_, pt. i.
(Giessen, 1860), &c. For the Greek Church: Pitra, _Juris ecclesiae
graecorum historia et monumenta_ (Rome, 1864); the later history of
the Greek law: Zachariae, _Historiae juris graecorum delineatio_
(Heidelberg, 1839); Mortreuil, _Histoire du droit byzantin_ (Paris,
1843-1846); the recent texts in the _Conciliorum Collectio lacensis_,
vol. ii.; _Acta et decreta s. conciliorum, quae ab episcopis rituum
orientalium ab a. 1682 usque ad a. 1789 indeque ad a. 1869 sunt
celebrata_ (Freiburg, 1876). Short manual of Institutions: Jos.
Papp-Szilagyi, _Enchiridion juris eccl. orientalis catholicae_
(Magno-Varadini, 1862). For recent canonical texts: Richter's edition
of the council of Trent (Leipzig, 1863); the _Collectanea S.C. de
Propaganda Fide_ (Rome, 1893); the _Bullarium_, a collection of papal
acts and constitutions; the editions of Cocquelines (28 vols., Rome,
1733-1756), and of Cherubini (19 vols., Luxemburg, 1727-1758), which
are better than the enlarged reprint of Turin, which was unfinished
(it goes up to 1730). The official edition of the _Bullarium_ of
Benedict XIV. (4 vols., Rome, 1754-1758) has been reprinted several
times and is of great importance; the continuation of the _Bullarium_
since Benedict XIV. has been published by Barberi, _Bullarii romani
continuatio_, in 20 vols., going up to the fourth year of Gregory X
