Abstract

Reports results of a study of the phenomenon of retrieval overlap. Three studies reported that retrieval overlap was small, and analysis of the overlap data shows that the overlap items are much more likely to be rated as relevant to the search topic. Moreover, the odds are at least 2 to 1 that overlap items are judged to be definitely relevant. This retrieval overlap may be used as a search tactic if searchers are interested in a few items of definite relevance: Although multiple retrieval could be derived from different searches or different search methods, it appears that online searchers could easily incorporate this search tactic by searching different databases when a few definite relevant items are called for
