This paper describes the use of a document delivery test (DDT) to measure the availability of biomedical research journals in South African health sciences libraries. The methodology employed was developed twenty years ago by a team of researchers from the Institute for the Advancement of Medical Communication under the direction of R. H. Orr. The testing of the methodology was in itself an objective of the present research. A citation pool consisting of 307 items was constructed from references to journal articles in papers published in 1989 by South African biomedical researchers. The availability of each article was determined at each of seven medical library sites; the performance was measured and presented as an arithmetical value or document delivery capability index (CI). The results of the tests show a high level of availability, ranging from CI = 81.68 to CI = 92.97 for the journals sampled. The DDT methodology was found to be practical, applicable to such studies, and flexible. Its use is recommended for similar studies.

Health sciences libraries that provide fee-based information services must consider and develop policies and procedures for complying with legal requirements. This paper reviews the provisions of copyright law that pertain to document delivery, including two court decisions concerning copyright. Also discussed are recent actions by publishers to reinforce their view of libraries' responsibilities for royalty fees for articles copied and their use of licenses to impose additional restrictions on the use of and reproduction of materials.
The Geisinger Medical Center Library implemented a GRATEFUL MED outreach project in rural north-central Pennsylvania directed at providing physicians access to current medical literature. A total of 1,327 physicians affiliated with twenty-three hospitals practice in a thirteen-county area the size of the state of New Jersey. Of these hospitals, only four have hospital libraries, which vary in size and in staff abilities to meet the information needs of their affiliated physicians. The outreach project encompassed two stages--demonstrations of GRATEFUL MED and LOANSOME DOC at county medical society or hospital meetings, and installation and training in individual offices. The eighteen-month project ended in March 1992. Statistics were collected for the number of GRATEFUL MED software packages loaded (sixty-two), the number of document delivery items supplied by Geisinger Medical Center Library to project participants (367), and the number of physicians attending introductory demonstrations or follow-up training programs (455 at sixty-eight sessions). By the end of the project, 147 (32%) of those who had attended a seminar had access to GRATEFUL MED.

Many hospitals are unable to maintain a full-or even half-time professional librarian to support the professional and nonprofessional hospital staff, and to assist with the development of education programs. To answer this need, the Cleveland Health Sciences Library has developed the "circuit rider librarian" concept. A designated librarian from the staff visits a group of hospitals and, for a fee, provides library service which the hospital could not or would not readily supply for itself. The only limitations on the expansion of such a program are the interest of the hospitals, their geographic proximity to each other and to the resource library, and the ability of the latter to handle the increased demand.
Information gathered from Grateful Med and Loansome Doc outreach projects, including one involving seven health centers in rural southwest Alabama, raises questions about the effectiveness of such programs. This paper presents a review of the literature on Grateful Med as well as of information access and usage behaviors of physicians, an overview of the Alabama project, and data from other projects. Analysis of the responses and observations of the researchers reveal some strategies for enhancing the outcomes of such projects and improving access to medical care literature by health care professionals at rural sites.
The nature of the fiscal crisis in health science libraries in the United States is in part due to the style of management in these libraries, in part due to the lack of user identification, in part due to the lack of economically valid fees for service, and in part due to the success of the Biomedical Communications Network. These issues are discussed in terms of how they might be approached. A pragmatic stance is advocated for practitioners, the MLA, the NLM, and library schools to jointly address the questions raised.
A study of the 1975 borrowing requests made by all hospital libraries in central western Massachusetts showed that there were 4,368 requests for articles contained in 1,071 different periodical titles. The numbers of requests per title ranged from eighty-nine for one title to one for each of 123 titles. A graph of the data showed a geometric progression, and the Bradford constants for this dispersion averaged 1.28. The percentage of total requests related to the age of requested issues varied from 62.48% for items not over five years old and 78.15% for issues not over ten years, to 95.57% for materials not over thirty years old. Bradford constants averaged 2.13. Of the thirty most requested periodical titles, sixteen were published in foreign countries, as follows: England--ten; Netherlands--three; Australia--one; Canada--one; and Sweden--one. The study's significance included its total coverage of a relatively large and isolated region, its focus upon the records of requesting rather than lending libraries, and its analysis of interlibrary rather than in-house activities.

OBJECTIVE: Experts disagree on the parameters to use to identify the "best" serials within a scientific field. The author set out to develop an extension to Dhawan's journal selection model for ranking serials in any scientific field. METHODS: Comparison of three different instantiations of Dhawan's model were used to rank thirty-four biomedical informatics serials. RESULTS: The first instantiation of Dhawan's model identified seven serials and divided them into two groups. The second instantiation of Dhawan's model identified twelve serials and separated them into two groups. Using fuzzy set theory the new extended model produced a rank ordered list of the top twelve biomedical informatics serials. CONCLUSIONS: Use of fuzzy set theory to assign set membership and combine data in Dhawan's journal selection model allows one to: (1) eliminate the need to determine arbitrary cutoff points for inclusion of serials within each of Dhawan's evaluation criteria categories, (2) combine data from disparate sources, and (3) obtain a rank-ordered list of the biomedical informatics serials rather than simply identifying a set of the "top" serials. Such a ranked list provides librarians and researchers alike with the information necessary to help them make their biomedical informatics serial selection decisions based on objective, quantifiable data.
