A reader has just alerted me to the existence of an on-line databank of secondary literature on Augustine. Based on the Augustinus-Lexikon
and the Corpus Augustinianum Gissense
, the database has compiled some 27,000 titles into an on-line bibliography, accessible via a wide variety of search strings (a minimal familiarity with German may be necessary to navigate the site). Hat tip to David of Cosmos, Liturgy, Sex!
