    Abstract
    Research conducted in the early 80's has shown that subject access is still one of the most dominant approaches in OPACs. However, while some of the subject searches result in no recall, others often retrieve so much that users are discouraged to proceed further. These and other problems were investigated and solutions were found in improving search methods (such as word stemming, extending search to full bibliographical record and providing end user thesaurus) and indexing techniques (such as ny enhancing subject headings with table of contents and back of the book indexes or by traditional systems). More recent research indicates that the real answer to the question of 'precision without sacrificing recall' lies in the developing 'user friendly novel interfaces' and also in designing 'knowledge based systems', wherein sers would not be expected to learn query formulation or even to be familiar with the indexing language of the system. Several interesting studies and research projects on the subject have produced a whole gamut of information, but one can still visualise the evolving trends of research vis-a-vis their future prospects as possible solutions
