OBJECTIVES: To help those preparing patient information by developing a search protocol for finding evidence on treatments that would maximize rigour, relevance and completeness. To apply the search protocol in one example area, 'early breast cancer'. METHODS: Development--a multidisciplinary group listed evidence sources and assigned them to 'rigour of methods' bandings and also assessed their completeness. A search protocol was made by ranking evidence sources by rigour and then by completeness. Application-the protocol was used to search for information on treatments for early breast cancer. RESULTS: Eighteen evidence sources provided details of their methods. Thirteen sources were assigned to Band A ('key source') and two sources to Band B ('some doubt about rigour but nevertheless useful'). The 15 Band A and B sources were ordered into a search protocol and used to identify 24 pieces of evidence about early breast cancer. Ten reviews were excluded (as irrelevant), leaving 14 useful pieces of evidence-based information to help inform patient information. CONCLUSIONS: Those preparing patient information on treatments for early breast cancer would find 14 pieces of useful evidence. It remains to be seen how far these pieces of evidence would answer questions that patients might pose about treatments.
Development and implementation of the Biocommunications Network in the Memphis region have relied on sharing of resources among hospital libraries. Implied in this system is the recognition that all health care professionals have a right of access to health sciences libraries.

Communication flow of scientific information has been restructured with the development of new technologies and the Internet and their impact on social relations worldwide. The production of scientific knowledge has also been influenced by these cultural, social and economic changes and has contributed to new patterns of scientific communication. The objective of the study was to present the traditional scientific communication model and its evolution to electronic scientific communication stimulated by the use of electronic media and Internet and networking. While the traditional model is based on printed publications, the new one focuses on electronic publishing and open unlimited access to published literature. The challenges faced are in using all the potential of electronic media for improving traditional communication flow of scientific information and defining policies to support the new model of scientific communication to ensure quality, preservation and dissemination of information as a common good.

The internet is an excellent medium for storing and quickly disseminating large amounts of information on a global basis. Modern medicine requires a rapid access to information including clinical data from medical records, bibliographic databases, knowledge bases and nomenclature databases. This is especially true for university hospitals and medical schools for training as well as for fundamental and clinical research for diagnosis and therapeutic purposes. Therefore, the internet with its constantly increasing offers plays a more and more important role in scientific research. This review focuses on how developments of this communication technology have become a useful educational resource in medicine, and describes modest ideas in computer network use. Internet basic resources are electronic mailing (e-mail), discussion groups, file transfer, and browsing the World Wide Web (WWW).

The National Library of Medicine's (NLM) monographic resources in the medical behavioral sciences (MBS) were examined to assess NLM's ability to support the needs of researchers writing in this area. A sample of 239 representative monographs derived from citations in MBS-related articles published in 61 journals in 1981 were evaluated. These monographs were limited to works published between 1978 and 1981, inclusive. The subject distribution of the sample included fourteen of the twenty-one main classes in the LC classification, although BF (psychology), H (social sciences), and R (medicine) constituted 80.3% of the sample. The study revealed that NLM held 48.5% of the sample. The holdings of ten research medical libraries, including six of the seven regional medical libraries, were also evaluated in order to gauge NLM's ability to support that element of the medical library network. The holding rates of these libraries ranged widely (9.6% to 36%), although NLM was found to have far more extensive holdings overall, and when assessed against classes BF, H, and R. Overall, NLM could have supplied from 28.8% to 44.5% of the monographs not held by the medical libraries. In only a few cases were the ten medical libraries able to provide access to monographs not held by NLM. The findings of the study indicate that, regardless of NLM's indication of support to the MBS area, the holdings of more general research and academic libraries are essential to support the monograph needs of MBS researchers.

Increasing numbers of physical therapists are providing evaluation and therapy in their own private-practice clinics. Their move out of the hospital setting has reduced their access to the sources of information designed to support clinical and practice-management decision making. The author designed a survey to determine how often physical therapists in private practice in Vermont use seven sources of information for clinical and practice-management decision making. Survey respondents also were asked to rate the anticipated usefulness of a variety of health sciences library information and research services not currently available to them and to rank access paths to information according to their preferences. The therapists' responses show frequent reliance on personal and office collections of professional literature for clinical decision making but virtually no use of bibliographic databases. Respondents ranked document-delivery services and mediated searches as having the greatest anticipated usefulness for clinical decision making. The limitations of their current information-seeking behavior and their high level of interest in increased access to a wide range of information and research services make physical therapists in private practice of special interest to health sciences librarians who are planning outreach programs.
