Dictionnaire d'Archéologie Chrétienne et de Liturgie
This is a 15-book set published in 30 volumes between 1907 and 1953, in French.
The volumes up to Book 5, Part 1 were published before 1923, and are
in the public domain in the United States.
Below we link to online copies of these public domain volumes. All the volumes
from this period were published under the supervision of Fernand Cabrol and Henri Leclerq.
This is a "meta-book", which stitches together separate files elsewhere on the Web as they appeared in a previously published book. It is subject to removal if someone produces an integrated edition. If that happens, The Online Books Page will point to the integrated version.
