Previous information retrieval research has neglected examination of older adults' search behavior. The present study examined the online search performance and associated errors of 54 older adult users of a representative online library catalog system. Participants' error data were examined in the framework of Borgman's three layers of knowledge needed to perform online library catalog searching: (1) conceptual knowledge, (2) semantic knowledge, and (3) technical skills in executing the query. The results of older adults were consistent with findings of previous online library catalog studies with younger adults. Older adults experienced serious problems at all three knowledge layers but experienced their most severe difficulties with conceptual knowledge of how to search the online library catalog system (e.g., formulating queries, understanding and using keyword and Boolean searching, and understanding the contents of databases). The significance of these findings for older adults' use of online library catalogs will be discussed.  相似文献

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

Online catalogs are more than an extension of the card catalog. They are something entirely new and under continuous de- velopment. Although users are enthusiastic about online catalogs. their ositive attitude may change unless certain problems are cor- rectef The library profession should develop specifications for on- line catalogs that w~ll help eliminate user problems. Online catalogs interact with the user and can give himlher a sense of control if more modes of access for effective retrieval are designed. Online catalogs of the future should be more efficient if librarians have greater input in their design.  相似文献

Online public access catalogs (OPACS) enable the user to search a library's holdings in ways never before possible and to know the status of the desired items before going to the shelf. Serials constitute an important part of a library's collection. Holdings information is a necessary adjunct to bibliographic information. The online catalog of the future will give access to serial literature beyond that held by a library. As users become accustomed to the OPAC's capabilities their expectations for access to information will rise. Libraries should be aware of the factors to be considered when incorporating serials information into an online catalog. They must make decisions on what information their users need and what form of access and display will best meet that need.  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

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

The purpose of this study is to obtain information which would help planners of the online catalog design a catalog which would be relevant to the needs of university faculty. Data was obtained by means of a questionnaire mailed to the faculty, College of Humanities, University of Utah. It was found that (1) references in books or articles they read; (2) the Subject Catalog; and (3) printed indexes, bibliographies and research guides in that order were the three most utilized information sources. Browsing was an important fourth. The faculty would like more in-depth coverage of the local library collection rather than access to other library catalogs or online databases from the catalog terminal. Feedback and comments in response to an open-ended question varied.  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

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

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:
  1. As a Web-analytic tool Google Analytics provided extensive information on the OPAC and the navigational behaviors of users.

  2. Fifty-eight percent of our users visited the Web site regularly.

  3. The most popular search method, which was employed by 37% of our users, was by title.

  4. 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.

  5. Suggestions were made by the authors to improve the users’ search experience of the catalog Web site.

This study is significant to libraries with Web catalogs because it demonstrates the potential value of using Google Analytics as a Web analytics tool in combination with the OPAC transaction logs to measure catalog usability.  相似文献

Abstract

Libraries in Latvia, as in other Eastern European countries, have begun implementing automated systems. This article outlines the state of automation in Latvian libraries and discusses the problems associated with providing subject access in their computerized catalogues. Issues relating to subject searching and retrieval in Latvian online catalogues (MARC, keyword vs controlled vocabulary search, stemming and truncation, subject headings and thesauri, retrieval mechanisms, use-system interfaces) are discussed. Recommendations are made for further progress in Latvian online catalogues in general and for subject access in particular. User education and general library concerns (classification, retrospective conversion, data exchange and networking) are also considered.  相似文献

This paper describes the procedures used at the Library of the College of Physicians of Philadelphia to divide its ninety-year-old dictionary card catalog. The division was necessitated by overcrowding, obsolete subject headings, and lack of a complete authority list which resulted in like materials being scattered throughout the catalog under several headings. Two catalogs were created: the historical-biographical catalog, representing all works published before 1950 and all works of historical or biographical nature; and the current catalog, containing all works published from 1950 on, excepting historical or biographical materials. The 1950- catalog was further divided into name and subject catalogs, and the subject section was revised according to MeSH. The project was completed in about two years. As a result, searching time has been much reduced, and the library is able to take advantage of the annual revisions of MeSH to update the subject catalog.  相似文献

The name main-entry heading has been a source of controversy throughout the history of Anglo-American cataloging with debate being closely tied to author identification. It is not surprising that debate has gained momentum as the functionality of online library catalogs and the costs of cataloging are under increasing close scrutiny. Following an historical overview of the name or author main-entry heading, this article discusses the finding and identifying functions of online catalogs as they relate to authorship. The article concludes that the name main-entry heading is an essential component of online catalog citation displays through which catalog users decide the usefulness of retrieved cataloging records.  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

This article illustrates the collaboration of three entities- the library, its online system and the authority service vendor-to achieve online authority control in a medium-sized academic library efficiently and cost-effectively. The authority service vendor checks and revises (as needed) the headings of the library's new bibliographic records, providing new authority records for them. Through a separate notification service, the vendor also provides revised authority records for the existing authority file, alerting the library when in-house online maintenance is needed. In this online environment, authority records and bibliographic records are maintained automatically by the vendor authority service. Thus, using various authority heading reports which can be generated by the local online system in conjunction with the notification service, the library concentrates its authority work on the elimination or correction of obsolete headings. The authority vendor services are effective and reduce the cost of maintaining the online catalog. Ultimately, accurate standardized headings enhance the ease and effectiveness of online searching and retrieval for all who consult the library's catalog.  相似文献

Abstract

In the 1990′s, school library media specialists must stress their expertise as teaching professionals in order to make informed decisions relating to the automation of library catalogs. The cognitive paradigm provides a user-centered perspective of the information retrieval process and confirms the problematic nature of the new technology for children. By applying the cognitive viewpoint to online information retrieval, school library media specialists can help guide system design and plan instructional programs that are developmentally appropriate for children.  相似文献

Abstract

Library pathfinders are a time-tested method of leading library users to important resources. However, paper-based pathfinders suffer from space limitations, and both paper-based and Web-based pathfinders require frequent updates to keep up with new library acquisitions. This article details a step-by-step method to create an online dynamic pathfinder with a clean, intuitive interface that performs predetermined searches in online library catalogs. This tool leads users to resources much as a traditional pathfinder does, but it is always up-to-date, requires almost no maintenance, and familiarizes patrons with the library's catalog as they use it. This article requires a basic knowledge of HTML. PHP and JavaScript are also used. While knowledge of these languages is helpful, these parts of the dynamic pathfinder are described in enough detail that no prior knowledge is required.  相似文献
