    Abstract
    A research project in progress at Middlesex Polytechnic is examining the problems of providing adequate subject access from MARC-based cataloguing systems. Various forms of printed index are being evaluated and an experimental OPAC is being designed. The PRECIS RIN file will be tested as a basis for online thesaural control and as a browsing facility
