This article critically examines four Google search products (Google Advanced Search, Google News Advanced Search, Google Books Advanced Search, and Google Advanced Scholar Search) and shows how each uses metadata to enhance or improve search results. In addition, the article shows how metadata can increase search precision and recall in information discovery systems. From a library perspective, this article analyzes some of the metadata-enabled features of Google's advanced search pages and compares these features to those found in a typical online library catalog. From a serials perspective, Google News Advanced Search demonstrates how Google indexes news websites, sites that are essentially continuing resources. As Google incorporates more and more metadata functionality into its advanced search pages, they increasingly begin to function more like online library catalogs and less like search pages found in a traditional Internet search engine. The simple search box has many limitations, and like libraries, Google is increasingly creating and offering metadata-enabled search features that improve search precision and recall in its products. 相似文献

In this article, research carried out in Iran illustrating new developments in knowledge organization is reviewed. For this purpose, all relevant studies were identified and classified into three categories: (1) studies focusing on conceptual models; (2) studies focusing on the RDA standard; and (3) studies focusing on online library catalogs (OPACs), metadata, and labeling formats related to RDA and FRBR. LIS dissertations and theses were reviewed and categorized into these three groups. The results of each research were categorized. At the end, the research methods applied in these researches were analyzed and some suggestions for further studies are proposed. 相似文献

The availability of U.S. Government Printing Office bibliographic tapes for copy cataloging or for loading directly into online catalogs may have lulled documents librarians into believing that the problem of bibliographic control for documents collections has been solved. Others may believe that with the move to an electronic distribution system for United States government information, creating and loading bibliographic records for government publications into local library catalogs is becoming an anachronism. This article discusses the functions of cataloging in light of continuing needs and current developments in access to government information. Recommendations are made for ways that the library community, providers of government information, and automation specialists can work together to reexamine bibliographic standards, expand tape loading to non-U.S. depository documents collections, link useful bibliographic databases with library catalogs, and use cataloging of Internet resources to show relationships between physical collections and remotely accessible government information. 相似文献

Some types of publication are viewed by librarians as serials and by publishers as monographs. In the pre-digital environment, cataloging rules and library workflows were developed to manage these publications. The shift to electronic publishing, distribution, and access brings new considerations into play. This article describes current cataloging practice and examines the effects of these shifts on library catalogs and user access through them. 相似文献

Web-scale discovery service systems and platforms are continuing to evolve and become more commonly adopted in academic libraries. Functioning as more than next-generation catalogs due to their volume and associated Web services, they invite strategic inquiry and launch libraries into deeper questioning and continuous critical thinking concerning discovery system best practices. This article explores emerging library discovery positions and discovery requirements gleaned through position postings from Autocat, Code4Lib, ERIL-L, and NGC4Lib listserv e-mails, from February 2012 through July 2014, along with a 2013 scan of Association of Research Library (ARL) staff directories’ Web sites. As seen through the lens of recent discovery position postings and names of discovery positions at ARL libraries, staffing solutions suggest strategic oversight and deep understanding of discovery systems, metadata, and users. This study of 36 discovery positions reveals directors or managers as comprising the highest number with ten (28 percent), systems with eight (22 percent), cataloging and metadata with seven (19 percent), acquisitions or electronic resources with five (14 percent), user experiences with three (8 percent), access services with two (6 percent), and general technical services with one (3 percent). These emerging discovery positions traverse both traditional technical and public services functions, with the majority, 26 (72 percent), from large research-level institutions. 相似文献

Abstract Popular for their ability to provide full-text linking, OpenURL link servers, such as SFX, can also interface with online catalogs and interlibrary loan modules, giving library users the ability to locate articles in print or request items not owned by their local institution. This article examines four different approaches to integrating print holding information into SFX, detailing the advantages and drawbacks of each approach. The ultimate goal is to provide end-users with comprehensive, dynamic access to the full range of core library services, including online full-text, print materials, and interlibrary loan. 相似文献

The deployment of information services through mobile apps is an innovative plan to provide effective services to end users. Libraries can promote and expand their existing information services by offering mobile apps to access electronic resources, the library Web site, online catalogs, and institutional repositories. This article discusses a realistic approach to enhance library services through mobile applications. The present study focuses on mobile applications adopted in the library of Gogte Institute of Technology. It also discusses the working module, features, and framework of mobile apps. 相似文献

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

Abstract Mounting digital images of art objects on a Web site is only the first step in providing patron access to such materials. Libraries and museums have a responsibility to provide not only high-quality digital reproductions but also high-quality access from an integrated library catalog with controlled vocabulary and consistent access points. While some digital collections may have excellent internal searchability and require no more than collection level cataloging in a library's OPAC, others may demand cataloging of individual components of the collection. A particular collection's significance, its potential audience, the types of access required, as well as factors such as its size and cohesiveness need to be considered before becoming locked into a specific Web designespecially when it is that of another institution. This paper examines several online library catalogs in which records for art objects as well as historical objects and natural history specimens have been merged, with varying degrees of success, and briefly addresses a modest proposal to catalog ceramic objects at the Ohio State University Libraries. The importance of consistent subject access in a merged catalog, regardless of the thesaurus or thesauri used, is stressed. Library consortia and bibliographic utilities may offer an economically appealing alternative for libraries that cannot design and construct their own digital libraries but these external organizations often have limited capability for-or interest in-modifying the design for a particular library and even less interest in cataloging the collections. Libraries, too, must be faulted for simply listing available electronic resources, either alphabetically or in broad subject categories, on a separate portion of their Web page and failing to provide full catalog records in their catalog. Finally, it is emphasized that the current debate over the viability of MARC 21 versus other metadata standards remains largely irrelevant to the importance of continuing to cultivate a monolithic online catalog, maintaining cataloging standards, and not mindlessly developing what amounts to a separate, rudimentary catalog solely for electronic resources. 相似文献

This article discusses problems in the management of library e-resources and attempts to identify potential solutions to the problems. By describing an e-resources enhancement project taken by Rutgers University Libraries, this article points to the importance of providing contextually rich metadata and reorganizing the accessibility of e-resources on a library's website. It introduces how this Rutgers project adopted the National Information Standards Organization Metasearch Initiative to support the identification of appropriate e-collections for metasearching. The outcomes of the project have facilitated a dynamic display of relevant e-resources to library users as an effective way of automatic access to library e-collections. 相似文献

Abstract Like many other libraries, the Science, Industry and Business Library (SIBL) of The New York Public Library instructs customers in using the Web. In addition, the library is using the Web to further educate and assist its customers. SIBL provides Web access to its catalogs, a Web menu for the selection of electronic databases, Web guides for doing research in various subjects, and Web-accessible instructional materials. The library is also planning Web-based tutorials for its site which will reach a new, remote audience. Remote access to learning opportunities will enhance and extend traditional library services. 相似文献

Library catalogs do not provide catalog users with the assistance they need to easily and confidently select the person they are interested in. Examples are provided of Web services that do a better job of helping information seekers differentiate the person they are seeking from those with similar names. Some of the reasons for this failure in library catalogs are examined. This article then looks at how much information is necessary to help users disambiguate names, how that information could be captured and shared, and some ways the information could be displayed in library catalogs. 相似文献
