    Abstract
    This paper reports on an evaluation of the browsing behaviour of end users of a WWW-OPAC focussing on the browsing relevance feedback (BRF) strategy. Results of this study reveal that BRF is a popular strategy. We also find that the relationships involved in the BRF strategy are generally syntagmatic
