AbstractDistance Learning Library Services at the University of Kentucky provided an electronic reserves service as a pilot project for distance learning courses in the 2000–01 academic year. Distance Learning Programs, which is a part of the Distance Learning Technology Center, funded the project. Policies and procedures were formulated, an account was set up with the Copyright Clearance Center, and the service was marketed. Our first electronic reserves were available for the Fall 2000 semester. 相似文献

A thesaurus has been developed to serve as the integrating unit for the computerized information storage and retrieval system of the Vision Information Center. The Center maintains records of information in the visual sciences which are available to the user in the forms of computer-assisted instruction, literature retrieval, and patient records. The numerical coding system used in the thesaurus permits seven levels of specificity; this specificity is required for depth of indexing, as well as to limit the retrieval to those bibliographic citations which are relevant to a highly specific search request. The flexible design of the thesaurus facilitates frequent revision and addition of new terminology. 相似文献

The University of Florida Health Science Center Library (UF-HSCL) surveyed MEDLINE end-user activities of the faculty from the six colleges which the UF-HSCL serves. A questionnaire was developed and sent to all faculty members. The Basic SAS program was used to analyze the collected data. This survey was intended to identify the users, the reasons for faculty members not being end users, the purpose for searching MEDLINE, the information retrieval methods, the level of end-user satisfaction, and the librarian's role in information retrieval activities. Many findings from this survey were in agreement with those of the 1988 study by the National Library of Medicine. 相似文献

Rensselaer Middle High School has all the fiscal and social problems of a small inner city school, but critical thinking and independent learning are central to the curriculum. Learning Center programs include a grade 6-12 interdisciplinary research skills program, an automated library, and a field trip program to local public and college libraries. The hectic participation by students, the cooperation of the administration and city, and the active teaching role of the Librarian make it all work. 相似文献

Starting with two computer terminals in 1972, the Health Sciences Learning Resources Center of the University of Minnesota Bio-Medical Library expanded its instructional facilities to ten terminals and thirty-five microcomputers by 1985. Computer use accounted for 28% of total center circulation. The impact of these resources on health sciences curricula is described and issues related to use, support, and planning are raised and discussed. Judged by their acceptance and educational value, computers are successful health sciences learning resources at the University of Minnesota. 相似文献

To permit easy user access to an uncataloged serials collection, a method was devised to produce (via computer facilities) a book catalog. This book catalog includes both an alphabetical listing by serial title and a subject section that lists titles by appropriate category. The programs necessary for this system were designed in the computer center according to specifications outlined by library personnel. The catalog can be easily reproduced from the computer printout and distributed campus-wide as well as used within the Learning Resources Center. 相似文献
