Title

User persistence in displaying online catalog postings : LUIS

Abstract

User persistence in displaying postings is a significant human factor in the design of computer driven information systems, including online catalogs. Expert opinion and a study of users of a first generation online catalogue have suggested that users normally display no more than 30 to 35 postings. A follow up study on a second generation system with a larger database found that a greater proportion of users reported overload, but 100 postings (rather than 15) were considered 'too many'. Partially persistent users typically displayed 28 postings, but overloaded uses did not outnumber totally persistent users until postings retrieved exceeded 200. The findings suggest that, given sufficient resources, designers should still consider 30 to 35 postings typical persistence, but also justify treating 100 or 200 postings as a common threshold of overload
