Case Studies/Cologne-based Libraries
All bibliographic data from Cologne-based libraries in Germany are available to the public with no known copyright restrictions. Cologne-based libraries who surrendered their copyrights using the CC0 public domain dedication include the University and Public Library of Cologne (USB), the Library of the Academy of Media Arts Cologne, the University Library of the University of Applied Science of Cologne, and the LBZ. The data is currently linked from the North Rhine-Westphalian Library Service Center (hbz).
The Cologne-based libraries, in cooperation with the North Rhine-Westphalian Library Service Center (hbz), surrendered all copyright and related or neighboring rights to their bibliographic data using the CC0 public domain dedication.
The Cologne-based libraries chose to release their data in the spirit of Open Access movement, following on the heels of the library of the European Organization for Nuclear Research (CERN), who already published its data under a public domain license in January 2010. With so much library data now in the public domain, there emerges greater potential synergy for libraries and the Semantic Web. In a joint statement, the Cologne-based libraries note that "Freely supplying bibliographic data should not only further enhance cooperation among libraries but enable subsequent use by non-library institutions" and that "The North Rhine-Westphalian Library Service Center has recently begun evaluating the possibilities to transform data from library catalogs in such a way that it can become a part of the emerging Semantic Web. The liberalization of bibliographic data provides the legal background to perform this transformation in a cooperative, open, and transparent way."
