The Catholic Encyclopedia, Volume 1: Aachen to Assize

The need of a Catholic Encyclopedia in English was manifest for many
years before it was decided to publish one. Editors of various general
Encyclopedias had attempted to make them satisfactory from a Catholic
point of view, but without success, partly because they could not
afford the space, but chiefly because in matters of dispute their
contributors were too often permitted to be partial, if not erroneous,
in their statements.
