Long-term Preservation
The Digital Library of the Bavarian State Library has been engaged in long-term preservation activities since 1999. In cooperation with the Leibniz Computing Center, it has worked on a comprehensive organisational and technical infrastructure for long-term archiving since 2004. In the context of a two-year pilot project, a comprehensive new infrastructure was developed. It allows an efficient and largely automated ingest and archiving of the data as well as access to the data via existing online catalogues and subject gateways. Fortunately the times of the "archive" consisting of an ordinary wooden locker with several hundred CDs and DVDs are history since 2004.
Together with the Leibniz Computing Center, the Digital Library runs one of the largest electronic archives in Germany. At present (October 2007), the archive contains an overall amount of 45 terabytes of data (more than 22 million files). Redundant storage and regular migration measures guarantee the long-term preservation of the data.
