The Biographisch-Bibliographisches Kirchenlexikon (BBKL) is a German biographical encyclopedia covering deceased persons related to the history of the church, philosophy and literature, founded by Friedrich Wilhelm Bautz, the first volume of which appeared in 1975..
It features over 20,000 articles, many of which were made freely available online between 1996 and 2011.[1] The online service now operates on a subscription model. Though, courtesy of the Internet Archive, some such entries remain available as archived pages and many of the print volumes are available to read online (with free registration).
