This paper presents data from two statewide ILL studies conducted in Illinois in 1995/96 and 1999/00. The results from the two studies provide a longitudinal look at borrowing and lending in Illinois and with the second study confirm a journal resource-sharing model for the state. Further analysis of high-use titles was conducted to determine any impact the present availability of full-text electronic journals is having on ILL, and the potential impact full-text access to highly-requested titles could have on resource sharing in Illinois. 相似文献

MEDLINEplus: building and maintaining the National Library of Medicine's consumer health Web service 总被引：1，自引：0，他引：1
MEDLINEplus is a Web-based consumer health information resource, made available by the National Library of Medicine (NLM). MEDLINEplus has been designed to provide consumers with a well-organized, selective Web site facilitating access to reliable full-text health information. In addition to full-text resources, MEDLINEplus directs consumers to dictionaries, organizations, directories, libraries, and clearinghouses for answers to health questions. For each health topic, MEDLINEplus includes a preformulated MEDLINE search created by librarians. The site has been designed to match consumer language to medical terminology. NLM has used advances in database and Web technologies to build and maintain MEDLINEplus, allowing health sciences librarians to contribute remotely to the resource. This article describes the development and implementation of MEDLINEplus, its supporting technology, and plans for future development. 相似文献

GOOGLE学术搜索工具及其在我馆的应用 总被引：2，自引：0，他引：2
分析了Google学术搜索在学术资源服务体系中的积极作用。Google学术搜索继承了Google的优点,吸引了大批用户。它基本上可以正确地甄别资源的学术性,在搜索的效果方面也有不错的表现,在弥补图书馆对公开获取资源的资源服务方面,起到很好的补充作用。但是也有不足之处。比如没有考虑用户的资源环境,不能很好地解决“合适版本”的问题,不能避免用户的无效链接现象。最后介绍了北京师范大学图书馆对Google学术搜索的理解和实际应用的做法。以及通过参加Library Link计划,将Google学术搜索成功纳入图书馆学术资源服务体系的成功案例。最后的统计数字说明Google学术搜索在该校起到了很好的资源服务作用。 相似文献

Developing a research library for a new university provides the challenge and the opportunity to test some ideas currently prominent within academic librarianship and to use new information technology in an unprecedented way. A philosophical commitment to building an “electronic library” affects planning and management decisions at every stage. This library is committed to supporting university teaching and research programs by providing access to bibliographical citations, abstracts and full-text material, based on what is available in a discipline, not just what has been acquired by the library; “access over ownership” is not just a current slogan but a basic element in decision-making. 相似文献

As the world's largest online full-text resource of business, news, legal, and medical information, Mead Data Central's LEXIS®, NEXIS®, and MEDIS® services pose special implementation and instructional challenges for academic reference librarians. This paper discusses such issues as telecommunications access, printing/downloading policies, staff education, and instructional strategies necessary to consider before offering this value-added reference service in an academic library. 相似文献

This pilot study examined the use of PDQ (Physician Data Query)--a user-friendly, full-text, cancer database--as a clinical information resource on an oncology unit. The twenty-nine participants included faculty, hematology-oncology fellows, residents, interns, medical students, pharmacists, and nursing staff. During the one-month study, PDQ was available twenty-four hours a day at the nursing station via a microcomputer. Participants were trained to use PDQ and allowed to search the database as prompted by clinical situations. The project evaluated the use of PDQ, as well as clinicians' perceptions of its usefulness. Results indicate that access to PDQ on an oncology unit provides an excellent educational and clinical resource. Fifty-one percent of the participants used PDQ an average of 2.4 times each. Heaviest users were medical trainees (78%), although 39% of nurses became users. Over half of the PDQ users reported that use of the database affected clinical care. 相似文献

Evidence-Based Medicine Reviews (EBMR) is a new full-text product from Ovid Technologies. EBMR supports the practice of evidence-based medicine (EBM) by providing access to two premiere EBM resources: the Cochrane Database of Systematic Reviews from the international Cochrane Collaboration, and Best Evidence from the American College of Physicians-American Society of Internal Medicine. Both resources alert health care professionals, researchers, and librarians to clinically relevant and methodologically sound studies by providing access to full-text reviews and meta-analyses of clinical literature. Value-added features include links to EBMR from MEDLINE, alerting MEDLINE users to available reviews. An "EBM Reviews" limit within MEDLINE facilitates access to the EBMR database contents. 相似文献

Peer-to-peer (P2P) networks integrate autonomous computing resources without requiring a central coordinating authority, which
makes them a potentially robust and scalable model for providing federated search capability to large-scale networks of text-based
digital libraries. However, peer-to-peer networks have so far provided very limited support for full-text federated search
with relevance-based document ranking. This paper provides solutions to full-text federated search of text-based digital libraries
in hierarchical peer-to-peer networks. Existing approaches to full-text search are adapted and new methods are developed for
the problems of resource representation, resource selection, and result merging according to the unique characteristics of
hierarchical peer-to-peer networks. Experimental results demonstrate that the proposed approaches offer a better combination
of accuracy and efficiency than more common alternatives for federated search of text-based digital libraries in peer-to-peer
networks. 相似文献

There have been many recent changes to PubMed to enhance its usefulness. Those changes include: LinkOut Libraries (local holding field), PubMed Central (full-text articles archived by the National Library of Medicine), and LinkOut (access to full-text articles right from the PubMed citation). Medical librarians should be aware of how these features work to best assist their clients. These new features offer the possibility of true desktop access for library patrons. Not only will patrons appreciate these new features, but their use in libraries will literally change what we do, who does it, and how it is done. 相似文献

ABSTRACT The digitization of library materials has had a tremendous impact on libraries. By using the Internet, readers can access digital library materials from any place in the world. The BMCC Library started several programs to provide more digital materials to its patrons in the forms of electronic books, periodicals, full-text materials, and webpage links to other databases. A test program began in spring 2002 for course reserves, and electronic archiving was about to start in fall 2001. This paper describes a survey conducted to measure the response to the implementation of ERes for digitizing course reserves. 相似文献

Abstract Providing distance learners access to library services does not automatically translate into usage of those resources. The literature on information-seeking behaviour of distance learners has indicated that they prefer to use local resources, as well as Web-based resources. This study investigates perspectives on library services and available resources for distance learners in the Teacher-Librarianship by Distance Learning program at the University of Alberta, Edmonton, Canada. The findings suggest that distance learners in this program tend to rely on local and familiar resources, have a lack of awareness or understanding of certain library services provided to them, rely heavily on electronic full-text availability, and may feel isolated from fellow students, resulting in low collaboration in the process of accessing information. The researchers suggest developing effective marketing strategies and collaborating with faculty to promote usage of library services provided to distance learners. 相似文献
