Compared to libraries in Anglo-American countries, sociological evaluation methods are only rarely used by German libraries in order to measure the impact of training concepts on information literacy and to improve the teaching methods. The project TUBLIK (Tutoren- und Blended-Learning-basierte Vermittlung von Informationskompetenz) at the University Library of Heidelberg, which makes use of several social science methods, offers a starting point for addressing these deficiencies. With the methods applied, it was shown that students’ information literacy competencies have increased due to TUBLIK and it was possible to develop methodological proposals for optimizing the concept. It
also became evident that it is necessary to systematically develop evaluation methods for measuring information literacy and to build up expertise in social science methods at libraries.
