The Patrologia Latina Database is an electronic version of the first edition of Jacques-Paul Migne's Patrologiae Cursus Completus, Series Latina. The PLD contains all 221 volumes of the first edition of Jacques-Paul Migne's Series Latina, which includes the original 217 volumes (1844-1855) plus the later four volumes of indexes (1862-1865). The Patrologia Latina Database covers the works of the Church Fathers from Tertullian in 200 AD to the death of Pope Innocent III in 1216, including all prefatory material, original texts, critical apparatus, and indexes. Some major figures included are Hilary, Ambrose, Jerome, Boethius, Isidore, Bede, Peter Damian, Bernard, Augustine, Peter Lombard, Peter Chrysologus, and many others.
Migne's column numbers, essential references for scholars, are also included. Although the text is primarily in Latin, the database has an English-language search engine and help. A cross-search option allows users to find search terms in both the Patrologia Latina Database and the Acta Sanctorum Database. Also, Brill's edition of Jan Frederik Niermeyer's Mediae Latinitatis Lexicon Minus is available from the search page. Bibliotheca Hagiographica Latina reference numbers are also included.
