The fundamental corpus of patristic (and medieval) Christian writings was published by Abbe J.P. Migne in the nineteenth century in two series: Patrologia Cursus Completus: Series Prima (Latin texts) and Patrologia Cursus Completus: Series Graeca (Greek texts with Latin translations). Pius Library owns two sets of each series; one is in the Vatican Film Library; the other is in Lewis Annex. The library provides access for Saint Louis University faculty, staff, and students to the online version, the Patrologia Latina Database.
Migne reprinted pre-exisiting texts that were often antiquated even at the time he published them and errors were sometimes introduced in the reprinting process. Therefore, the scholar needs to consult a more recent critical edition if one is available. There are several important ongoing series of modern critical editions of early Christian writings (such as Corpus Christianorum) with which the student of patristics should be familiar. Basic information on these series can be found in Quasten's Patrology, vol. 1, pp. 13-16, Altaner's Patrology, pp. 38ff. (eighth German edition, pp. 38ff.), Poucet's Aux sources de l'antiquite greco-romaine, pp. 19-23 or Drobner's Lehrbuch, pp. xxxvii-xxxix or online information on Christian literary sources is available through the Bibliotheca Classica Selecta. For information on important series of English translations, see the references from Quasten and Altaner above as well as Robinson, Early Church, pp. 36-38.

Ref. BR66.5.D45 1995
"An extensive index to the published texts of the Latin church fathers" (Kepple, Reference Works) and the counterpart to the Clavis Patrum Graecorum (see below). Serves as a catalog of the authors already included or proposed for the Corpus Christianorum: Series Latina. The first four chapters are chronological starting with the antenicene writers and ending with the Venerable Bede. Subsequent chapters include listings for various genres and types of sources, e.g., grammarians and rhetoricians, lives of saints, etc. Each entry (i.e. title) is numbered; these Clavis numbers may be used to search the Library of Latin Texts. Four indexes: patristic authors and titles, subject, saints, and first lines. Concordance tables with other indexes (e.g. H.J. Frede's Kirchenschriftsteller, Verzeichnis und Sigel) or editions of texts (e.g. Migne's Patrologia Latina may be found at the end of the volume.

The fourth volume covers church councils (from the Council of Ancyra (314 A.D.) to the Trullan Synod (691 A.D.) and catenae. Included in the fifth volume are indexes of names and titles, bible and liturgy, first lines and concordance tables with other indexes (e.g. Bibliotheca Hagiographica Graeca) or editions of texts (e.g. Migne's Patrologia Graeca). A supplemental volume updating the information in the five earlier volumes was published in 1998.
