UnCover on the Web: search hints and applications in library environments

Among the huge maze of resources available on the Internet, UnCoverWeb stands out as a valuable tool for medical libraries. This up-to-date, free-access, multidisciplinary database of periodical references is searched through an easy-to-learn graphical user interface that is a welcome improvement over the telnet version. This article reviews the basic and advanced search techniques for UnCoverWeb, as well as providing information on the document delivery functions and table of contents alerting service called Reveal. UnCover's currency is evaluated and compared with other current awareness resources. System deficiencies are discussed, with the conclusion that although UnCoverWeb lacks the sophisticated features of many commercial database search services, it is nonetheless a useful addition to the repertoire of information sources available in a library.

An SDILINE profile oriented to patient care.

Hospital physicians naturally require current medical information in order to treat their patients. An objectively obtained SDILINE storesearch was devised to obtain this information. A rank-ordered list of hospital discharge diagnoses, coded with ICDA terms, was translated into MeSH. The top two Bradford zones of journals defined as useful at the University of Missouri--Kansas City were ANDed to these MeSH terms. Citations retrieved from the storesearch are input into an in-house computerized data base. The method can be easily used by other medical or hospital libraries without access to computers.
