The German National Library (DNB) is entrusted with the task of collecting, permanently archiving, bibliographically classifying and making available to the general public all German and German-language publications from 1913, foreign publications about Germany, translations of German works, and the works of German-speaking emigrants published abroad between 1933 and 1945. Together with other archiving libraries, archives and museums, the DNB ensures the controlled transmission of our national cultural heritage. Since 2006, the legal collection mandate of the DNB explicitly includes non-physical media works (online publications).
This talk illustrates how the collection of the DNB has changed in times of large scale digital publishing, examines the challenges, which long term archiving of and permanent access to digital media present to a national library, and shows how the DNB addresses said challenges. It is essential to the DNB to work together with others, nationally and internationally, to develop technical and conceptual solutions for long term archiving and permanent access, not least in nestor, the German network of expertise in digital preservation, the office of which the DNB hosts. The library sees its jointly useable long term archive as one building block in a national infrastructure for permanent access to digital data and documents.
