  abstract={Evaluation of digital libraries assesses their effectiveness, quality and overall impact. To facilitate the comparison of different evaluations and for supporting the re-use of evaluation data, we are proposing a new logging schema that will account for all kinds of data about users, systems and the user-system interactions. We present a novel, multi-level logging framework that will provide complete coverage of the different aspects of DL usage. The main focus of this paper is the user behaviour level, for which we describe the logging scheme in some detail. Based on this specification, we show how the various DL stakeholders can analyze the logging data according to their specific interests. In addition, specific analysis tools and a freely accessable log data repository will yield synergies and sustainablity in DL evaluation.}
