Abstract

The University Library Groningen, COWOG (Centre for Research on Higher Education) and PICA developed a computer assisted bibliographic reference and advisory system (CoBRA). It is an expert system that advises users of the University Library when they want to execute a search for literature on a certain subject. In fact, it produces custom made guides to the literature in the library. Explained is why the system has been built, the architecture of the system is outlined and some comments are made on aspects of implementing such a system, and the need for library cooperation to build expert systems
