The history of nursing education in America is briefly told, with the growth of education in institutions of higher learning emphasized. Two trends in nursing education are paralleled by similar developments in nursing literature. The growth of scholarship in nursing is also noted. It is pointed out that nursing is a discipline in its own right, and that training for leadership is required. Continuing education programs are mentioned, together with the increase in nursing literature. Integrated libraries for the health sciences are recommended.  相似文献

We consider some issues of the development of the national information infrastructure in the field of innovation, including a national system of accounting for the results of scientific and technical activities (RSTA) and a national new-generation research computer network (NNGRCN). The current state of the national system of scientific and technical information and its resources for information support of innovation processes are analyzed. In the context of further development of the Commonwealth of Independent States (CIS), we propose a Conception of scientific and technical support for programs and projects of NIS member-states in the field of innovation, making it possible to incorporate the existing innovation-oriented information resources into a joint distributed integrated information system as well as to create new information resources and technologies.  相似文献

An outreach project which juxtaposed technology (Grateful Med) and a human intermediary (a circuit librarian) to serve health professionals in a rural area of Illinois is described. The five goals of the project were: promote Grateful Med as a clinical tool; introduce circuit librarianship to Illinois; heighten the awareness of health professionals to the value of timely information services; increase the visibility of the resource library; and evaluate the impact of the two components, Grateful Med and circuit librarianship. While the project was well-received and enjoyed short-term success, sustaining the same level of information activity post-project has not been achieved. Insuring utilization of health information by remote health professionals may be characterized as a Sisyphean task.  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

Journal searching in non-MEDLINE resources on Internet Web sites   总被引:1,自引:0,他引:1  
Internet access to the medical journal literature is absorbing the attention of all relevant parties, i.e., publishers, journal vendors, librarians, commercial providers, government agencies, and end users. Journal content on the Web sites spans the range from advertising and ordering information for the print version, to table of contents and abstracts, to downloadable full text and graphics of articles. The searching parameters for systems other than MEDLINE also differ extensively with a wide variety of features and resulting retrieval. This discussion reviews a selection of providers of medical information (particularly the journal literature) on the Internet, making a comparison of what is available on Web sites and how it can be searched.  相似文献

Among the huge maze of resources available on the Internet, UnCoverWeb stands out as a valuable tool for medical libraries. This up-to-date, free-access, multidisciplinary database of periodical references is searched through an easy-to-learn graphical user interface that is a welcome improvement over the telnet version. This article reviews the basic and advanced search techniques for UnCoverWeb, as well as providing information on the document delivery functions and table of contents alerting service called Reveal. UnCover's currency is evaluated and compared with other current awareness resources. System deficiencies are discussed, with the conclusion that although UnCoverWeb lacks the sophisticated features of many commercial database search services, it is nonetheless a useful addition to the repertoire of information sources available in a library.  相似文献
