The SuUB is listed on the Library Index (BIX); a benchmarking index which measures the performance of German libraries. Initiated by the Bertelsmann Foundation and the "Deutscher Bibliotheksverband (DBV)", BIX measures and compares the quality and performance of participating libraries based on the following factors: services, usage, efficiency and development.

While library systems servicing larger universities have tended to under-perform in comparison to those delivering services to smaller universities, the SuUB has continued to participate in this benchmarking program as it is the only relevant instrument for measuring the key performance indicators of libraries in German-speaking countries.
