The Albert Einstein Science Park library serves three research institutions specializing in the Earth sciences. It recently launched a search engine which covers the library's digital holdings, the institutional repository for GeoForschungsZentrum Potdam, and 30,000 OA resources on Earth science worldwide. For details, see Roland Bertelmann's announcement on SOAF.

free of most copyright and licensing restrictions.
Removing the barriers to serious research.
