MeDoc is a two-year project sponsored by the German Secretary for Education and Research which has begun in September 1995. The project is being led by the Springer Verlag, the Fachinformationszentrum Karlsruhe, and the Gesellschaft für Informatik, its participants are six German universities. Further, there are about twenty pilot user institutions so that the system being developed can be tested for usability right away. The goal of MeDoc is to build the MeDoc system which is to help Computer Science researchers and students (primarily in Germany, but also all over the world) to find information relevant to them. This aim is going to be achieved by two means. Useful information will be provided to the researchers and students by building a full-text database of ``critical mass''; on the other hand, the MeDoc Information Brokering System (IBS) will provide transparent access to existing bibliographic and full-text databases. The paper presented focuses on the latter part, the IBS.
