简述新一代OPAC出现的背景、基本特征及建设中存在的问题。标准化对新一代OPAC的技术创新、普及与推广、开放接口的开发具有重要的促进作用。OPAC标准化包括三个方面的内容:制定术语标准;以已有的软件质量系列标准为依据,建立OPAC质量评估标准体系,并促使OPAC开发商取得ISO 9000质量管理体系认证;建立一整套独立于具体实现技术,跨平台、跨语言、支持第三方系统便捷访问的OPAC开放接口标准。 相似文献

图书馆OPAC与图书搜索引擎、网上书店的功能比较和启示 总被引：9，自引：0，他引：9
OPAC即联机公共书目查询系统,是利用计算机终端来查询馆藏数据资源的一种现代化检索系统。OPAC与图书搜索引擎、网上书店三者具有相同的基本功能：查询、揭示图书,但图书搜索引擎、网上书店以其检索界面简洁友好、检索功能强大、书目信息丰富、排序科学化、用户互动性好,冲击威胁着图书馆OPAC。因此,图书馆OPAC应借鉴图书搜索引擎和网上书店的做法,改进OPAC功能、增加书目记录的可见性、建立各种独立于图书馆集成系统的新型OPAC。 相似文献

ABSTRACT Although there is a proliferation of information available on the Web, and law professors, students, and other users have a variety of channels to locate information and complete their research activities, the law library catalog still remains an important source for offering users access to information that has been evaluated and cataloged by experts. The usability of the catalog needs to be effectively measured before any necessary improvements can be made. This study was undertaken to investigate the information retrieval patterns of users of the Rutgers Law Library Online Public Access Catalog and to develop the catalog into a more effective search tool for these users. This study used an experimental approach to measure the usability of our catalog by analyzing the transaction logs from the OPAC system and the results from Google Analytics. The findings provided not only important information on user demographics and their computer systems, but also more insight on the search behaviors of users. The specific findings included the following:
-
As a Web-analytic tool Google Analytics provided extensive information on the OPAC and the navigational behaviors of users.
-
Fifty-eight percent of our users visited the Web site regularly.
-
The most popular search method, which was employed by 37% of our users, was by title.
-
Most patrons used computer systems with a high resolution and color depth monitor and visited the catalog Web site with a high-speed Internet connection.
-
Suggestions were made by the authors to improve the users’ search experience of the catalog Web site.

Efforts at networking and cooperation have flourished for some time at the University of the West Indies (UWI), a regional institution in the English-speaking Caribbean. Due to their common mission and shared goals, libraries within the system have collaborated on projects to enhance the services provided to their clients. In its attempt at collaboration, the Mona Campus established the UWI Mona Information Network, the primary goal of which is the creation of a campus-wide online catalog with member libraries having access to a larger pool of resources. Most of the departmental libraries within the system have struggled with their inability to adequately acquire and provide access to their collections. To this end some of these libraries have collaborated with the UWI Library to have their holdings added to the online public access catalog (OPAC). This article presents an overview of the collaborative efforts of the UWI Mona Libraries. 相似文献

ABSTRACT The Fresnes public library chose to enhance its bibliographic catalog by loading the complete backfile and regular updates of the BNF authority files. This unique solution allows them to put an end to local cataloging (notably subject assignment and the maintenance of the subject index) and to considerably reduce the “cost per title cataloged” based on the formula proposed by ISO Standard 11620: Information and Documentation—Library Performance Indicators. The authority files improve the quality of online services: they reduce the number of unsuccessful searches, reduce aberrant responses and allow for numerous OPAC possibilities; they offer library staff a valuable aid in their mission of assisting the public; they facilitate and improve the tasks of collection development and management. The new information system anticipated for the opening of the new library in March will give the authority files a larger role. Beyond assisting the simple catalog search, the authority files will function as a search engine for the whole network. The CD-ROM and DVD-ROM readers, and a selected number of Internet sites will, in fact, link to the authority files (notably subject and corporate author files) by the authority record number, using the same headings as in the library catalog. 相似文献

ABSTRACT Librarians at the Arnold Bernhard Library of Quinnipiac University were concerned with the usage levels of their electronic reference titles. They added the titles to the library's Web page, made individual records in the online catalog, and even established links between an OPAC keyword search and a search through electronic reference titles. It was still felt that the collection was underutilized. In 2007, the Automation Librarian began a project to add one more level of access to these titles—a graphic interface that simulated the process of walking into a reference room and picking out a title. A preliminary version was loaded in the Fall of 2007, and early results indicate that it has found an audience. 相似文献

基于Web3.0的OPAC构想 总被引：4，自引：1，他引：3
OPAC作为用户访问图书馆资源的门户,体现了图书馆的服务能力和水平,在信息技术高速发展,文献类型快速增长的今天,传统的OPAC不能满足用户的需求。利用Web3.0技术与理念,使OPAC脱离ILS的束缚,建立检索范围广泛、书目内容丰富、文献内容相关联、检索高效准确、检索结果按相关度排序、以用户为中心、读者高度参与的OPAC,可以将图书馆的服务延伸到图书馆之外,提高图书馆资源的利用率。 相似文献

联合书目系统是图书馆联盟内资源共享的前提和基础,虚拟联合目录是联合书目发展的方向,但虚拟联合目录存在检索结果集合并与排序难度大、成员馆检索压力大等缺点。为此,本文提出了一个由OPAC、馆际服务器和联盟间服务器组成的层次式虚拟书目系统,能更好地处理检索结果集、减轻成员馆的检索压力,该系统易扩展,更适合图书馆联盟不断发展壮大和联盟间不断融合的发展趋势。 相似文献
