The 10th volume of the catalogue series "Die handschriftliche Überlieferung der Werke des Heiligen Augustinus", edited by the Church Fathers Commission of the Austrian Academy of Sciences, lists the libraries and archives of East Germany as well as the re-united manuscripts of former West- and East-Berlin. Part 1 (Werkverzeichnis) contains the (pseudo-)Augustinian works and also provides - apart from Augustine´s sermons - a listing of those texts which are in the codices attributed to the Church Father, although it can be proved that they were written by other identified authors. Also included were translations of (pseudo-)Augustinian works into modern languages; part 2 Bibliotheksverzeichnis) contains all the manuscripts (about 1100) ordered by location and signatures. Furthermore, it provides the descriptions of the codices that got lost during or after World War II. During the work on the catalogues six previously unknown Augustinian sermons were found at Erfurt University Library (Bibliotheca Amploniana), which caused a sensation in scientific circles. All in all, most of the texts turned out to be spuria of the high and late middle-ages. They were - as far as possible identified, thereby providing a better overview of the reception of the church father´s oevure, not only for editors of Augustine, but also for a wider range of users such as medievists, historians and theologists. Two indices (one of authors, the other listed by initials) give quick access to the information required.
