Senior pastor Mag.a Dagmar Wagner-Rauca, widow of the late Protestant professor for systematic theology, Univ.-Prof. Dr. Falk Wagner, who had passed away in 1998, donated the philosophical section of the private library of her late husband to the library of theology in 2012. As their final project thesis, four graduates of the university training course Library and Information Studies 2018/2019, Ms. Viktoria Bernreiter, BA, DI Melanie Grader, Sophie Mattersdorfer and Dr. Christina Traxler, treated this collection with the purpose of compiling a complete catalogue and of identifying those copies that contain handwritten comments by Prof. Wagner which are important for the scolarly work on his philosophical and theological reasoning. They kindly gave their permission to publish the outcome of their project on the home page of the library of theology.
