    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 .
