We are happy to announce that our Linked Data Service has expanded and now includes bibliographic data. In the year 2010 the German National Library (DNB) started to publish its authority data as linked data. Our Linked Data Service [1] has expanded and now includes bibliographic data. As part of this process the license for linked data will also be changed to "Creative Commons Zero" [2]. As a first step, the bibliographic data of the DNB's main collection (apart from the printed music and the collection of the Deutsches Exilarchiv) and the serials (magazines, newspapers and series of the German Union Catalogue of serials (ZDB)) have been converted. Henceforth the RDF/XML-representation of the records are available at the DNB portal [3]. This is an experimental service that will be continually expanded and improved. Closer information about modeling and further procedures can be found in the updated German documentation [4] and in the soon coming updated English documentation [5]. We welcome comments and questions on the wiki documentation site [1].
