The German Pavilion began to build a bibliographic database from 1972, and put it into use on 1976, and distributed its magnetic tape and CD-ROM versions to provide online retrieval services for readers. The database has 2.42 million records, which can be searched through telephone network, communication network, scientific network, European network and Internet. In addition, the library also provides the tape and disk catalogues of British and Italian national bibliographies, theme microfilms of German national bibliographies and ISBN index microfilms of national bibliographies. Developed a standardized database of group author names with the National Library of Berlin and the Bavarian Library, and established a standardized database of keywords with the Bavarian Library. German libraries have also carried out cataloging services for paper books for reference. Extensive bibliographic information services have provided great convenience for German libraries and become the basis of their daily services. In recent years, together with other library and information institutions, we have developed the open network system DBV-OSI-II project of the German Library Consortium. The museum is the sponsor of this project. This network system can realize document purchasing, description, retrieval and utilization nationwide, speed up interlibrary loan, and create conditions for the networking of European libraries and professional information centers.
The German Pavilion also participated in the European computer directory networking project organized by Europe. Together with Sweden, Belgium and the Netherlands, we have developed a software package to analyze and forecast the European book market for readers' reference.
In order to realize the exchange and utilization of global bibliographic data, IFLA has carried out two large-scale scientific research projects in Frankfurt Pavilion since 1990, namely, the global bibliographic control project and the international UNMARC format research, in which the German National Library has played an important role. In addition, Leipzig Museum has made great achievements in book protection. The library is rich in books and has a book protection center, which undertakes the book preservation and protection project carried out by IFLA. 1994 is equipped with a batch paper deacidification machine to deacidify acid-containing books, which is advanced in technology. At present, this library is the only one in the world with this kind of equipment and technology. 1998 the book protection center was separated from the library and became a limited company.
