Abstract With the transformation of the card catalog into the online public access catalog came the expectation of its increased functionality. For the most part, today's online catalogs perform an expanded list of tasks quite effectively. Bibliographic utilities, system vendors, and individual libraries continue to improve bibliographic retrieval by providing new and better services through the catalog. In spite of these improvements, many observers believe that online catalogs have reached their maturity. Today's information environment includes a wealth of material to which online catalogs cannot provide universal and up-to-date access. Increasingly, librarians are turning to federated searching portal applications to find a means of managing the flood of digital information that threatens to engulf users. This chapter describes essential functionality of such tools, suggesting directions and strategies for improving them. The author concludes that, while the online catalog will continue to function as the principal tool for access control of the library's physical collections, the federated searching portal will ultimately serve as the library's principal Web gateway to digital resources. 相似文献

Like many libraries, the Bridge Consortium (the shared library of Carleton College and St. Olaf College) had outgrown the existing catalog and needed to find an improved search interface for collections. Seeking something that would work with the existing Innovative Interfaces Inc.'s Millennium integrated library system, researchers explored everything from catalog enhancements provided by Innovative Interfaces to a completely separate, Web-scale discovery tool. For the past year, they worked to implement VuFind as a catalog overlay, continually customizing and enhancing it based on user feedback. At the same time, they continued to research a broader solution and recommended a discovery tool to their consortium leadership group that they believe will redefine student research at their colleges and give new shape and direction to their consortium. By thinking of discovery as more than a product and staggering their implementation, they were better able to meet their consortium's needs. This article details their evaluation process and provides reflection on the decisions made. Many libraries are considering Web-scale discovery products. As part of the process, they confront questions about open source tools, Web site redesigns, incorporating user feedback, and consortial needs. The researchers hope to contribute to these libraries' processes by outlining their process and considerations, and what they learned along the way to arrive at their current solution. 相似文献

Next-generation catalogs or discovery tools (NGCs) overlay existing bibliographic data and repackage it in displays that differ from the traditional catalog. Many implementations of NGCs have revealed errors, omissions, or inconsistencies in the underlying data that had not been apparent in the traditional catalog. This study explored the effect of NGCs on cataloging functions and catalogers in academic libraries, examining catalogers’ participation in the selection and implementation processes, identifying and correcting data problems, changes to procedures or workflow, and staffing. 相似文献

Mbooks are open-access, digitized books freely available on the Internet. This article describes the Auraria Library's experience of loading brief MARC records for Mbooks into its online public access catalog and looks at some of the issues that arose from the record-loading project. Despite the low quality of the records, librarians in Auraria Library thought that loading them into the catalog was advantageous because of the rich content in the collection and because many of the records could be improved using the global update functionality in the catalog. Making the records available through the catalog, as opposed to merely linking to the entire collection from the Library's Web page, was considered to be valuable because of the aggregation a catalog provides and because the Mbooks collection helped fill gaps in the Library's physical collections. As more open-access, digitized books become available, libraries will need to plan and manage how best to provide access to them. 相似文献

Web-scale discovery services (WSDs) are a widespread phenomenon sweeping university libraries across the world. In this article the authors discuss this trend and their experience working on a test server with the open source discovery layer VuFind. Developed by Demian Katz of Villanova University, VuFind’s potential to index not only the library’s catalog but also proprietary databases through the integration of application program interfaces (APIs) offers public libraries the opportunity to develop a seamless website-to-catalog experience, thereby building a true virtual branch for their patrons. 相似文献

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

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

ABSTRACT Web-scale discovery services promise fast, easy searching from a single Google-like box, pleasing users and making library resources more discoverable. Some librarians embrace the concept of giving users what they have come to expect from Google, while others are concerned that this will “dumb down” searching and undermine information literacy. In this article we explore the potential impact of Web-scale discovery tools on information literacy, focusing particularly on undergraduate research skills. We review the existing literature and present findings and experiences from two mid-sized academic libraries that have adopted EBSCO Discovery Service as their library home page portal. 相似文献

ABSTRACT “Discovery” is today's term for user-centered information searching and access. A growing number of libraries have embraced Web-scale discovery services (WSDS) featuring one-stop searching of libraries’ owned and licensed collections. Recognizing potential benefits to users of these systems, a mid-sized ARL library formed a discovery-tool committee in spring 2012 to explore selection of a WSDS in keeping with its values, vision, and institutional mission. This article explores “discovery” as it assesses WSDS performance and reports results obtained from a request to WSDS vendors to showcase the search power of their system with actual reference questions. 相似文献

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

As studies show, undergraduates needing information frequently begin their research in a search engine such as Google rather than a library online catalog. To test the efficacy of that research approach, a local usability study of fifty topics in ten disciplines of study was performed. In a comparison of WorldCat.org and Google Books to the library catalog, it was found that more than double the number of hits to library-held material was found by searching WorldCat.org than the library online catalog alone. It was also learned that twice as many hits to articles and material within a thirty-mile radius were found in WorldCat.org and Google Books as compared to searching the online catalog alone. These results suggest the need to improve the native interface of catalogs and for continued placement of resources outside the library catalog. 相似文献

Discovery layers and remote access are the standard way to access and find academic library resources, making metadata, link resolvers, and indexing important considerations at the time of selection and throughout the lifespan of an electronic resource. Collection development librarians must be aware of how resources will function with and appear in the library's discovery layer. This awareness is an opportunity for collection development and discovery librarians to share their knowledge and collaborate to provide the best discovery for the library's resources. This case study examines ways the Electronic Access and Discovery unit at Auraria Library has fostered that relationship. 相似文献

Since the Online Computer Library Center (OCLC) unveiled its WorldCat Local library catalog discovery layer in 2008, library instructors have debated how to incorporate this tool into their teaching. WorldCat Local's faceted searching brings both educational benefits and unexpected challenges to the classroom. Instructors frequently hold formal and informal discussions on such topics as which search features are most effective during teaching and which patron groups benefit most from this tool. The authors of this article surveyed instruction librarians at U.S. academic libraries that are using WorldCat Local in order to gather and organize this feedback. This article presents the findings of this survey. 相似文献

ABSTRACTAcademic libraries provide intellectual access (discovery and procurement) to the full text of electronic journal articles through traditional library technologies like discovery layers, link resolver software and knowledge bases. These technologies mainly rely on accurate title-level metadata to successfully deliver journal articles to library users. Open Access articles pose a difficulty for many participants in the e-journal supply chain, including libraries and publishers, as Open Access status is a property of the article, not the title. A review of the literature examines: the impact of Open Access on intellectual access through traditional library technologies, current proposed solutions, and emerging technologies. 相似文献
