Summary:

The proceedings of this workshop gather the latest experimental results from HERA and capture new trends in HERA phenomenology. Although the presentations are by experts, they are suitable for both theoreticians and experimentalists. H1 members also cover ZEUS results and vice versa. This volume serves to point out existing discrepancies between experimental data and theoretical predictions and to identify projects to take on in the future.
