PubMed® is an on-line literature database hosted by the U.S. National Library of Medicine. Containing over 21 million citations for biomedical literature--both abstracts and full text--in the areas of the life sciences, behavioral studies, chemistry, and bioengineering, PubMed® represents an important tool for researchers. PubMed® searches return…

Discusses the retrieval dimensions of data collection activity online and their influence on the research evaluation outcome to reinforce the link between online retrieval and bibliometrics. Topics include publication counts; citation analyses; citation databases from the Institute for Scientific Information; and data set isolation. (Author/LRW)

Discusses the growth in use and acceptance of Web-based genomic and proteomic databases (GPD) in scholarly communication. Confirms the role of GPD in the scientific literature cycle, suggests GPD are a storage and retrieval mechanism for molecular biology information, and recommends that existing models of scientific communication be updated to…

Database Tomography (DT) is a system which includes algorithms for extracting multi-word phrase frequencies and performing phrase proximity analyses on any type of large textual database. DT was used to derive technical intelligence from a near-earth space (NES) database derived from the Science Citation Index and the Engineering Compendex.…

Discusses the problems inherent in applying what is learned in a carefully controlled information retrieval (IR) research project to searching the scientific databases available through a large commercial database. STN International is used as an example. (five references) (LAE)

Use of online bibliographic databases in Mexico is provided through Servicio de Consulta a Bancos de Informacion, a public service that provides information retrieval, document delivery, translation, technical support, and training services. Technical infrastructure is based on a public packet-switching network and institutional users may receive…

Search terms and user aids are noted in review of databases covering historical material in the hard and social sciences--U.S. Political Science Documents, ERIC, Language and Language Behavior Abstracts, POPLINE and Population Bibliography, PsycINFO, Sociological Abstracts, Child Abuse and Neglect, GEOREF, International Pharmaceuticals Abstracts,…

Describes a unitized data system for a scientific database that stores descriptions of individual experimental steps as separate text-based subunits together with appropriate linking signals. Conversion of graphics into searchable text, use of natural language, and cost effectiveness are discussed. An example using a biology research paper is…

Describes a project that investigated the application and impact of electronic publishing techniques in areas of scientific and technical information in the Federal Republic of Germany. Areas discussed include the state of research, technology, and applications; reactions of publishers and authors; and ways in which databases are actually accessed…

Examines the potential of the World Wide Web as an information and bibliographic source for scientists. Analyzes through content analysis the Web pages retrieved by the major search engines on a particular date as a result of a query regarding informetrics, and compares results to data retrieved from commercial databases. (Author/LRW)

An increased publication rate has given rise to an increased dependence on indexing services for tracking and retrieving relevant literature. Discusses the problems associated with the fact that most computer databases encompass literature from the past 20 to 27 years. (DDR)

Discusses how the lack of information infrastructures supporting scientific and technical research hampers attempts to transfer certain information technologies, such as online database searching, to developing nations. It is argued that laserdisk information storage technologies, such as CD-ROM, conform more closely to the prevailing conditions…

Presents an algorithmic approach to addressing the vocabulary problem in scientific information retrieval and information sharing, using the molecular biology domain as an example. A cognitive study and a follow-up document retrieval study were conducted using first a conjoined fly-worm thesaurus and then an actual worm database and the conjoined…

Review of background and justification of computerization project initiated to automate information work covers design concepts; implementation; and major characteristics of databases (local versions of BIOSIS and INSPEC, union catalog of monographs from Library of Congress/MARC records, union catalog of serials from International Serials Data…

Describes a study which demonstrates that unintended logical connections within scientific literature, which potentially reveal new knowledge, are unmarked by reference citations or other bibliographic clues. Citation analysis of two separate literatures in biomedicine that have a logical link is used to support this hypothesis. (Author/CLB)
