Our work on digital libraries started in 1996 and has provided several web-based prototype implementations that had been heavily used. 1996/97 our work was funded by the BMBF within the German digital library project MeDoc, 1998/99 within a HSP3 project.

The goal of the MeDoc project was the design, implementation and evaluation of full-text information and publication services in the field of computer science. More than 25 universities and institutes  participated in this project which run until Dec. 1997. Several dozens of computer science textbooks and numerous  journals and technical reports have been brought online within several fulltext database servers, including one our group. In 1997, we converted the textbook Mehrrechner-Datenbanksysteme to HTML.

In 1998/99, we developed and brought online the first version of the Document Server of the University of Leipzig. It included all kinds of full text documents, in particular Ph.D. theses, habilitation theses, master theses, preprints, etc. Inclusion of new documents is made easy over a Web interface and requires a signed copyright statement of the authors. All documents are available in several formats (HTML, PDF, Postscript) and searchable in a flexible way.

We also developed a first multimedia-rich web representation for the Museum of Musical Instruments of the University of Leipzig. Since 1996, we were the first to provide a web opac for the computer science library. Since 1997, we provide a XML solution for maintaining the current directory of lectures (with detailed descriptions of lectures).
