This article discusses the development of a vertically oriented CD-ROM database product in the medical subdiscipline of oncology. Called OncoDisc, the CD-ROM is mastered by ISG. It contains three major information collections: (1) PDQ (a system of a series of files and a set of relationships; the user accesses the data through those relationships); (2) Cancerlit (the research literature that underlies the treatment information contained in PDQ), and (3) full-text articles. SearchLITE, the retrieval system, is written in C language and has been implemented on the the DEC VAX family and the IBM PC/XT and PC/AT. The disc provides a personal library of oncology information for immediate local use by the health professional; it requires no subscription to an online service, no telecommunications, and no online search charges.

This article describes the Indexing Aid Project for conducting research in the areas of knowledge representation and indexing for information retrieval in order to develop interactive knowledge-based systems for computer-assisted indexing of the periodical medical literature. The system uses an experimental frame-based knowledge representation language, FrameKit, implemented in Franz Lisp. The initial prototype is designed to interact with trained MEDLINE indexers who will be prompted to enter subject terms as slot values in filling in document-specific frame data structures that are derived from the knowledge-base frames. In addition, the automatic application of rules associated with the knowledge-base frames produces a set of Medical Subject Heading (MeSH) keyword indices to the document. Important features of the system are representation of explicit relationships through slots which express the relations; slot values, restrictions, and rules made available by inheritance through "is-a" hierarchies; slot values denoted by functions that retrieve values from other slots; and restrictions on slot values displayable during data entry.

The Neurological Information Network (NIN) of the National Institute of Neurological and Communicative Disorders and Stroke (NINCDS) was a loosely structured assemblage of a variety of information-transfer activities that existed for approximately 20 years, starting in the early 1960s. These activities included the Neurosciences Research Program at the Massachusetts Institute of Technology, the Parkinson's Disease Information Center at Columbia University, the Brain Information Service at UCLA, the Information Center for Hearing, Speech, and Disorders of Human Communication at the Johns Hopkins Medical Institutions, the Clinical Neurology Information Center at the University of Nebraska, the Cerebrovascular Disease Abstracts generated at the Mayo Foundation and appearing in the journal Stroke, and Epilepsy Abstracts published by Excerpta Medica. The article discusses primarily the sociopolitical factors that govern the creation and life of activities of the type enumerated.

The radical changes and improvements in health sciences libraries during the last quarter century have been primarily achieved through the leadership of the National Library of Medicine (NLM) in the application of technology and in the creation of a biomedical communications network. This article describes principal programs and activities of the National Library of Medicine and their effects on health sciences libraries: the Medical Literature Analysis and Retrieval System (MEDLARS), implementation of the Medical Library Assistance Act (MLAA), and defense of "fair use" of copyrighted material. The article briefly summarizes more recent Federal activities which directly affect access to and dissemination of health information and concludes with a summary of problems for which solutions must be found if health sciences libraries are to be prepared to meet the future. It is clear from comparing the programs described with current government attitudes that, although the Federal government has promoted advancement in the dissemination of biomedical information in the past, this trend is reversing, and Federal funding to libraries is decreasing while the cost of accessing information is increasing.

The National Technical Information Service (NTIS) addresses the issue facing all government information providers--justification of the activity on a cost/benefit basis--by being self-supporting. The user pays for the information provided on a cost-recovery basis. Within the NTIS, a new program adds to the resources available to the health professional and/or consumer. The Center for the Utilization of Federal Technology (CUFT) links information, Federal technology resources, and new technologies to new users, including the private sector, to facilitate commercialization and therefore enhance utilization. To bring the Federal research and development (R & D) community together with potential non-Federal users, CUFT provides information products and undertakes networking activities in its Office of Applied Technology. The program initiates the link from the public to private sector for commercialization of newly developed Federal technology in its Office of Federal Patent Licensing. Individual products and examples of successful projects addressing the health community and its concerns are described. The CUFT program is increasing its online availability to deal with the increasing volume of information available and the growing number of users in health-related fields as well as in other areas of Federal scientific and technical information.

Since its founding in 1937, the National Cancer Institute (NCI) has supported a substantial program of information dissemination. Two peer-reviewed journals, begun in 1940 and 1959, are supplemented by a congressionally mandated International Cancer Research Data Bank (ICRDB), established in 1972. The NCI has made available online databases of published cancer literature and cancer research in progress for the past decade, using the National Library of Medicine (NLM) MEDLARS system. Recently, a clinical-practice-oriented cancer-information system called Physician Data Query (PDQ) has been developed for access at the NLM, as well as through commercial database vendors. The impact of the NCI information programs is currently under prospective evaluation.

Official printer and sales agent for publications of the Federal government, the U.S. Government Printing Office (GPO) receives typed and electronic manuscripts from virtually every agency of government. Either in house or through commercial procurement, GPO provides typesetting, printing, and binding services to produce finished publications. GPO also disseminates these publications through the 1400 Depository Libraries and the Superintendent of Documents Sales Program. GPO employs an hierarchical marketing system which helps assure public exposure for every sales program title, while assigning increasing levels of promotion for titles with the greatest sales potential. As a trend, GPO sees fewer consumer-oriented publications and more professional-use titles. GPO also observes a new appreciation of the value of government statistical information, and increased agency efforts to provide improved public access to this data. GPO is working with publishing agencies and information-technology suppliers to study ways of accommodating demand for electronic information dissemination.

End-user searching of National Library of Medicine (NLM) online data bases during eleven years has been investigated through transaction logs, questionnaires, and follow-up interviews. From 1976 through 1984, pathologists and pharmacists performed 8,313 searches. Highlights of our studies are compared with a review of other end-user research. Volume of searching is directly related to the convenient placement of the terminal in the work place. Slightly fewer than half of all potential searchers actually search for themselves. Practices of pharmacists and pathologists do not differ in important ways. Nonmediated searchers feel they need answers more promptly than do those who obtain mediated searches. End-users perform very simple searches, mostly using only the AND operator. Problems with techniques are fewer and more easily solved than those with the vocabulary and content of the system. The major problems, with the most powerful capabilities of MEDLINE--subheadings and explosions--sometimes cause substantial loss of references, but in relatively few searches. One-on-one teaching is most popular, with trial-and-error the most frequent procedure used in actual learning.

This article reports on five separate studies designed for the National Library of Medicine (NLM) to develop and test methodologies for evaluating the products of large databases. The methodologies were tested on literatures of the medical behavioral sciences (MBS). One of these studies examined how well NLM covered MBS monographic literature using CATLINE and OCLC. Another examined MBS journal and serial literature coverage in MEDLINE and other MBS-related databases available through DIALOG. These two studies used 1010 items derived from the reference lists of sixty-one journals, and tested for gaps and overlaps in coverage in the various databases. A third study examined the quality of the indexing NLM provides to MBS literatures and developed a measure of indexing as a system component. The final two studies explored how well MEDLINE retrieved documents on topics submitted by MBS professionals and how online searchers viewed MEDLINE (and other systems and databases) in handling MBS topics. The five studies yielded both broad research outcomes and specific recommendations to NLM.

“A Navigator of Natural Language Organized Data” (ANNOD) is a retrieval system which combines use of probabilistic, linguistic, and empirical means to rank individual paragraphs of full text for their similarity to natural language queries proposed by users. ANNOD includes common word deletion, word root isolation, query expansion by a thesaurus, and application of a complex empirical matching (ranking) algorithm. The Hepatitis Knowledge Base, the text of a prototype information system, was the file used for testing ANNOD. Responses to a series of users' unrestricted natural language queries were evaluated by three testers. Information needed to answer 85 to 95‰ of the queries was located and displayed in the first few selected paragraphs. It was successful in locating information in both the classified (listed in Table of Contents) and unclassified portions of text. Development of this retrieval system resulted from the complementarity of and interaction between computer science and medical domain expert knowledge. Extension of these techniques to larger knowledge bases is needed to clarify their proper role.
