Comparing Computerized and Paper Based Information Retrieval Systems in Library Public Services: A Meta-Analysis.
Trahan, Eric
A meta-analytical literature review was performed on the literature in which computerized and paper based information retrieval systems were compared. Specifically, online catalogs were compared with card catalogs, and online bibliographic retrieval was compared with searching printed indexes. Studies which included information on relevance, precision, time, or costs of searching were selected. A total of 25 studies published between 1967 and 1989 met the selection criteria, producing a total mean effect size of -0.383. The analysis revealed that there were no significant differences between the two systems for the variables of relevance, time, or costs. The paper based systems were significantly superior on the precision variable. The variance in individual study results could not be explained by any of the factors that were included in the analysis. These factors included the publication date, publication mode, method of effect size computation, library environment, and search complexity. It is hypothesized that the variability in study methodology might explain the variability in study results. Specific recommendations are made for more standardized methods in future research in which information retrieval systems are compared. The individual study results are appended.
