The Patrologia Latina Database is an electronic version of the first edition of Jacques-Paul Migne's Patrologia Latina, published between 1844 and 1855, and the four volumes of indexes published between 1862 and 1865. The Patrologia Latina comprises the works of the Church Fathers from Tertullian in 200 AD to the death of Pope Innocent III in 1216. The database contains the complete Patrologia Latina, including all prefatory material, original texts, critical apparatus and indexes. Migne's column numbers, essential references for scholars, are included.

New features

This latest release of Patrologia Latina Database provides a number of improvements,

  • a single character internal wildcard
  • search history with ability to combine searches
  • ability to mark records and e-mail durable URLs and bibliographic information for specific volumes
  • ability to limit searches to a range of volumes

For customers who own both Patrologia Latina Database and Acta Sanctorum database a cross-searchable facility allows users to find entries on search terms and texts that are included in both corpora, in one search. As an additional resource, we have added Brill's edition of Jan Frederik Niermeyer's Mediae Latinitatis Lexicon Minus for users of both services. It provides easy reference to this essential resource of Medieval Latin studies and is not available in any other electronic format. Both databases provide Unicode functionality that allows full display of diacritics and Greek keyword searching and Bibliotheca Hagiographica Latina reference numbers.
