The modern bibliography of secondary literature on Augustine's thought and writing is immense. The best guides come from the Institut des Études Augustiniennes in Paris, published annually in the Revue des études augustiniennes. This is handsomely supplemented by the on-line bibliographical index of the Würzburg Augustinians. An earlier version of that resource is readily available on the CD-ROM published by Schwabe of Basel, "Corpus Augustinianum Gissense" (CAG), but that is now several years old already. I have reviewed CAG for Augustinian Studies, as well as the first volume of the landmark Augustinus-Lexikon that will, when finished, be a thorough and exhaustive guide to Augustine's world and work (with articles in multiple languages). In the meantime, I'm proud to have been associated with Allan Fitzgerald, OSA, and a distinguished editorial board in the creation of St. Augustine Through the Ages: An Encyclopedia, publishedin 1999 by Wm Eerdmans Publishing Company.
The following links take the reader to a variety of tools and studies that I have collected on the web since 1994. Additions welcome.
