This document summarizes a presentation on Linked Open Data given by Silke Schomburg and Adrian Pohl at the Bielefeld Conference on April 26, 2012. It discusses the basics of Linked Open Data (LOD), the motivations for adopting LOD practices, and the LOD activities of the hbz library network, including lobid.org for publishing open bibliographic data as LOD and culturegraph.org for interconnecting datasets. It also explores future opportunities for web-based cataloging and building a more integrated library infrastructure based on open data and web services.
