Describes the use of the Z39.50 information retrieval protocol as the basis for Infocal, a read-only, client/server-based campus information system. Technical considerations in adapting the protocol to nonbibliographic data, including semantic modules, dynamic attribute sets, and dynamic record syntax, are described in detail. (Contains 11…

Examines the practice and implications of issuing corrections, retractions, and amplifications in online databases. All database producers do not provide mechanisms to accommodate retractions and corrections, and it can be difficult for a searcher to find evidence of error correction. Sidebars illustrate both the lack of and evidence of…
