Abstract | Differences in judged relevance of Educational Resources Information Center (ERIC) abstracts identified by two different information systems were investigated. A national semi-private educational service agency which utilizes mechanical searching of the research literature was one information system, while the other was a regional, Federally-funded agency employing manual searching. Twenty clients reported they found substantially more ERIC abstracts identified by a manual method to be relevant to their needs than abstracts located by a mechanical searching system using the same set of ERIC descriptors.
