ABSTRACT Digital collections of full-text e-books are proliferating on the Web and provide a wealth of open content for students. To examine whether academic libraries are providing a digital gateway to these resources, ten e-book titles from open digital collections were searched in the online catalogs and Web pages of ten academic libraries serving distance learners. Only three of the digital collection e-books were available from any of the library catalogs, and none were found on library Web pages. Availability of the ten e-book titles through Google and other digital discovery tools also had mixed results. Continued projects for improved delivery of open online content are necessary. In order to fulfill their role as digital gateways for their academic communities, libraries must pursue metadata standards to support cross-searching, collaborative projects, and development of e-resource search software, which integrates with the library catalog. 相似文献

数字图书馆个性化服务的实施与策略 总被引：1，自引：0，他引：1
调查分析个性化服务和社会计算工具在数字图书馆的现状,探讨该种服务对数字图书馆发展的影响。选择29个具有代表性的数字图书馆的网站进行调查,结果发现约31％的抽样对象提供某种类型的个性化服务,包括个性化电子邮件通知,个性化界面,检索行为保存,个性化动态链接和同行推荐。通过对5种社会计算工具在抽样对象网站上的实施情况进行调查后认为,个性化服务和社会计算具有提高数字图书馆功能和使用的潜力,未来应加强最优化实施策略和应用效果方面的研究。 相似文献

开放资源互操作协议OAI研究 总被引：9，自引：0，他引：9
随着数字图书馆的发展,各种资源间的互操作性也变得越来越重要,人们也一直致力于对分布式资源进行统一检索的开发。要实现这一目标,归纳起来有三种方式:代理模式,即通过检索代理对不同的目标源分别检索,然后对检索结果统一处理;联邦检索模式,即各个目标源严格遵守统一标准或协议从而实现底层的跨库检索;采集模式,即通过元数据采集协议将分布的元数据集中提供检索。本文对这三种模式进行了对比介绍,并对国际上应用越来越广泛的 OAI 元数据互操作机制及应用进行了详细介绍和讨论。 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

联邦检索系统对图书馆和信息服务机构的各种数据库和网络资源进行整合,使信息资源用户“单点登录”、“一站购齐”的理想得以实现。但联邦搜索引擎和检索系统在实践中还存在资源全面集成、数据库优化选择、去重机制、检索结果个性化排序等一系列问题,值得软件开发商在联邦检索系统完善中加以重视,以便为联邦软件的广泛应用提供良好的技术支撑。 相似文献

Summary The emergence of federated search tools for the library market represents a significant step toward the longstanding goal of a common searching interface in the reference environment. These systems aim to provide integrated access to library resources of all types. This article describes and evaluates federated search tools from four vendors. It suggests criteria that may be useful for libraries attempting to compare and contrast this type of access tool. 相似文献

Google Scholar is a free service that provides a simple way to broadly search for scholarly works and to connect patrons with the resources libraries provide. The researchers in this study analyzed Google Scholar usage data from 2006 for three library tools at San Francisco State University: SFX link resolver, Web Access Management proxy server, and ILLiad interlibrary loan server. Overall, the data suggested that Google Scholar had become a very useful resource in the library and was a significant addition to the library's collection of research databases. SFX data revealed requests from Google Scholar grew ten-fold from 2006 to 2011, and that Google Scholar became the top-ranked SFX source for requests in 2011. Library patrons favored Google Scholar over San Francisco State University's federated search tool, MetaLib, and it has become an important source for interlibrary loan requests. Analysis of San Francisco State University usage data will assist other libraries in their decisions about the implementation of Google Scholar. 相似文献

本文对JALIS特色资源的整合进行了调查,调查显示全省各馆建设的特色数据库特色鲜明、建设规范,但新增资源少,服务面窄,特色数据库的作用有待进一步发挥,各馆一致认为有必要对特色数据库统一整合。特色资源整合平台可以首先对每个特色数据库进行元数据的收割,同时应尽可能收割或采集全文资源,对采集不到的资源应提供多种链接方式或文献传递来保证全文资源的获取,并提供统一检索、学科导航、特色库还原、资源评论、RSS订阅等功能来提高特色资源的服务效果。 相似文献

��[Purpose/significance] Study the service status of digital badge certification learning in American university libraries, and provide inspiration and reference for the related services of domestic university libraries.[Method/process] Through the search engine, the digital badge column of the official Website of the American university library was investigated, and the foreign language literature review and research was conducted through the professional foreign language database to investigate the basic status of the service of digital badge certification learning, and analyzed the American library. The digital badge identified the way and content of the learning service.[Result/conclusion] American university libraries pay attention to the design of "game-style" hierarchical digital badge mechanism, motivate students to learn, select and perfect the platform that matches the digital badge, find the cooperation institution to give digital badges more value. It is used for librarian business training to improve the professional quality and service level of librarians. Digital badges can promote the improvement of information literacy education in university libraries, and the application and promotion of digital badges is an opportunity for university libraries to enhance their status. 相似文献
