WELCOME to the home of the largest Catholic Encyclopedia resource on the web.
The Catholic Encyclopedia (TCE) was published in 15 volumes between 1907 and 1912 by the Robert Appleton Company. In 1913 the publisher, renamed as Encyclopedia Press, Inc., released a new edition. A year later (1914) a comprehensive Index was released as Volume 16.
This Original Catholic Encyclopedia (OCE) site holds the complete 16 volume set with the original text of all articles (~11,500) faithfully preserved.
Catholic Answers began the process of creating an authoritative reproduction of this classic, world-renowned reference by scanning 14,000+ pages from the original volumes and processing the scans with OCR software. Issues that arose from the scanning/OCR process were addressed by a team of Catholic editors and technicians. All TCE content on this site was produced by Catholic Answers directly from original Catholic Encyclopedia print volumes.
