This paper explores surviving documentation and what it reveals about the underlying social structure and relations in a historic time and place. The mid-nineteenth century is chosen as a period prior to modern bureaucracies so that documents are not found in defining filing systems. Some six hundred documents are studied individually and characterized collectively. They are examined not to tell a story, however, but for evidence of their creation and maintenance and of their physical types, functional characteristics, and relations between authors and recipients. The study reveals the fruitfulness of such an orientation to documents, which complements traditional historical uses that emphasize document content.  相似文献

In 1991, the Reference and Information Services staff of the Alfred Taubman Medical Library at the University of Michigan gathered data on the use of the reference desk, including the frequency and types of assistance requested by different user groups throughout the year. Recommendations based on the results of this study led to improved service as well as more efficient use of staff resources.  相似文献

The purpose of the study was to identify the pattern of publication about women and AIDS in scientific journals. Bradford zones were identified in each of six databases. The study determined that journal scatter for this subset of AIDS literature differed from the scatter in the general literature; further, the information indexed in the six electronic sources demonstrated little overlap. Consequently, key journal and newsletter titles identified by this study should form the core of any collection focusing on women and AIDS. The assurance of quality patient care management demands that librarians consult multiple resources for information retrieval that can assist health care providers, patients, and caregivers to enhance quality of life as well as to provide optimum care.  相似文献

Benchmarking is a quality improvement tool that is increasingly being applied to the health care field and to the libraries within that field. Using mostly resources assessible at no charge through the Internet, a collection of information was compiled on benchmarking and its applications. Sources could be identified in several formats including books, journals and articles, multi-media materials, and organizations.  相似文献

Before planning for provision of Consumer Health Information Services, the librarian and administration must anticipate the problems encountered in sharing funds, personnel, space, and materials with an existing medical or patient education library. Establishing new space within or outside the hospital, or participating in community projects which meet consumer health information needs, are important considerations for planners. This article sets forth the place of some CHI services in the hospital setting, and how they relate to other library services. Differences between hospital library support for Patient Education and for Consumer Health Information services are discussed.  相似文献
