- Abstract
- Designing research on the retrieval effectiveness of computer searches on PRECIS compared with retrieval effectiveness of searches on other types of subject analysis used in computer-based information sources is a complex process. This paper explores the complexity of measuring comparative retrieval effectiveness through a comparison of the subject analysis provided by the PRECIS system for fifty articles with the subject analysis provided for the same articles by three computer-based information sources: ERIC/CIJE, LLBA/Online and PsycINFO. Objectives are: (1) to discover factors that should be taken into account when designing this type of research; and (2) to identify extraneous variables that work against internal validity in research design .

- 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
