This paper gives suggestions to librarians on how to get started with electronic mail. It discusses the cost- and time-saving advantages of using electronic mail rather than TWX, United States mail, or telephones for communicating ILL requests and messages. For instance, preliminary cost data show that electronic mail is often half as expensive as TWX and costs no more than a 22 stamp. Key management concerns that must be considered when setting up electronic mail are discussed, including the need for subscribers to agree on one system. Also covered are the types of equipment that can be used with electronic mail, including print terminals. 相似文献

The need for a cost-performance analysis of TWX-mediated versus mail-mediated ILL requests is presented. Three hypotheses are proposed: (1) Unit cost for TWX-mediated ILL requests is greater then for mail-mediated ILL requests; (2) Completion time is shorter for TWX-mediated ILL requests than for mail-mediated ILL requests; (3) An analytic model can be developed that can be used to generate administrative data concerning a TWX installation. The data presented support all three hypotheses. It is shown, also, that through the use of this model a library can arrive at a cost for service of TWX versus mail-mediated ILL. 相似文献

Libraries now have available to them a variety of ways of speeding the flow of information among widely scattered locations. One of the means for the improvement of interlibrary loan service is the use of the teletypewriter, and the use of Teletypewriter Exchange Service (TWX) by medical libraries during the past three years is described. The background of library applications of teletypewriter systems is outlined, and the advantages, types of use, cost factors, and experiences of some groups are discussed, as well as the impact of the "network concept" on library service. 相似文献

The paper reviews the highlights of a four-week trial period (November 19-December 18, 1970) during which the Medical Library of the University of Virginia experimented with a new remote-access bibliographical control and retrieval system via its TWX machine. The system, called AIM-TWX, was sponsored by the Lister Hill National Center for Biomedical Communications and utilizes a timeshared IBM 360/67 computer in Santa Monica, California. Citations from 109 clinically-oriented journals from 1966 to date, including those currently included in the Abridged Index Medicus, may be retrieved either on- or off-line.Various aspects of this service are described, including problems of staffing, training, and record keeping, as well as the role of the MeSH vocabulary which is the principle "language" of the man-computer dialog.The statistical results indicated that the system was used for approximately 200 minutes on nineteen days and that an average of sixteen searches were run on any given day, or about 4.6 searches per hour of use. In spite of an inexperienced staff who had little knowledge of the MeSH vocabulary and whose training schedule was limited to one four-hour session, the experiment was highly successful in terms of searches and citations.At the end of the period, 298 searches had been run for 114 requestors, and 5,343 citations had been produced. Only fifty-five searches yielded no citations. The experiment generated a great deal of excitement and interest among the staff of the Library and of the Medical Center. Moreover, a large number of medical practitioners in large and small communities of Virginia participated in this experiment, indicating that there exists a great demand for this type of literature searching which AIM-TWX is able to provide with great rapidity. 相似文献

As electronic serials have shifted from being the exception to the norm, libraries are becoming increasingly reliant on knowledge base-driven systems to help manage electronic serial holdings. In 2011, the University of Toronto Libraries migrated its electronic resource holdings from a local database to a commercial electronic resource management (ERM) system. With two years of experience using a commercial ERM system, the presenters endeavored to analyze how the library is coping with e-serial management within this new environment. This study reveals many of the benefits and pitfalls of managing electronic journals within a knowledge base–driven system and highlights the need for greater standardization within the data supply chain, better communication with publishers and knowledge base providers, and increased collaboration to improve the e-resource management process. 相似文献
