In university libraries, reference librarians often get ambiguous questions to which they try to give appropriate answers. Because of limitations on resources, time, and mental capability for information processing, the decision-making process involved in answering reference questions becomes bounded by the rationality of these constraints.…

Identifies current trends in the automation of indexing, of information retrieval, and of interaction between the system and the users. Topics discussed include location, navigation, and indexing; digital libraries; matching documents to queries; weight of concepts; query structure, including fuzzy sets; algorithms; stemming; clustering; users'…

Applies theories about organizational information processing to better understand the influences on method of access and on effects of using online information. Explores the extent to which organizational differences also influence these variables, what the positive and negative outcomes from using online commercial databases are, and how those…
