Abstract
In the article the results of two provenance research projects that took place at Vienna University Library (VUL) between 2004 and 2010 are discussed and successful restitutions are described. The projects concerned VUL special and departmental libraries and the Main Library. In mid-2010 the two projects were merged into one project working group that took over its agenda. The process of merging the previously separate projects and the combined analysis of the existing data are described through the example of the French printed materials supplied to Vienna University Library by the GESTAPO.
