This document summarizes a presentation on e-book lending through public libraries in Germany. It discusses the growth of e-book lending since 2007 through a centralized service. Key points include how the service works by negotiating licenses with publishers and allowing patrons to download digital files for a limited time. Challenges addressed are limited formats, devices, and loan periods supported as well as the need for improved technology integration. The presentation also reviews promotion efforts and the future outlook, hoping for new license models, easier technology, and more compatibility.
