In the Dewey Decimal Classification (DDC) Online Project, subject searching and browsing of DDC Schedules and Relative Index were featured in an experimental online catalog. The effectiveness of this DDC in an online catalog was tested in online retrieval experiments at four participating libraries. These experiments provided data for analyses of subject searchers' use of a library classification in the information retrieval environment of an online catalog. Recommendations were provided for the enhancement of bibliographic records, online catalogs, and online cataloging systems with a library classification. In this paper, subject searchers' use of the subject outline search capability of the experimental online catalog is described. This capability was unique to the experimental online catalog and all other online catalogs, because it referred searchers to online displays of the classification schedules based on their entry of subject terms. Failure analyses of subject outline searches demonstrated its specific strengths and weaknesses. Users' postsearch interview comments highlighted their experiences and their satisfaction with this search. Based on the failure analyses and users' interview comments, recommendations are provided for the improvement of the subject outline search in online catalogs.  相似文献

This study analyzes the relationship between online public access catalog (OPAC) searches entered in a small academic library's catalog and the circulation of items during the same time period. Rather than identifying all searches resulting in a reasonable number of retrievals as successful, searches in this study were determined most useful if items on the results list were subsequently borrowed from the library. This comparison of search results with subsequent material checkouts indicates which metadata elements seem most useful to searchers, and suggests ways libraries might use this knowledge to enhance their users’ search experiences.  相似文献

Summary

This study examines the search tactics used by Web users to start their searches and deal with search problems such as too many postings and no relevant postings. Four search topics were developed to allow for comparison of search tactics used in four types of searches. The tactics analyzed include search statements, number of search statements, starting points, and tactics to solve the two search problems mentioned above. Search statements were searched in Alta Vista to determine their success and their nature was analyzed. With regard to the tactics used to address search problems, t-tests and chi-square tests found no difference between searches for texts and searches for graphic information, and between known-item searches and subject searches. Some of Web users' search tactics were similar to those for online searching or online catalog searches, but several tactics were unique to Web searching.  相似文献

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

The increasing availability of computerized information sources and networking capabilities, along with the proliferation of microcomputers in faculty homes and offices, has led to increased demands for direct access to databases. The librarian's role as online search intermediary appears to be changing from performing searches directly to aiding users in doing their own searching. The Research Libraries Information Network (RLIN), one of the major cataloging utilities, offers a wealth of bibliographic information in both its online union catalog, and its many specialized files. The University at Albany Libraries participated in a pilot project involving faculty end-user access to RLIN. This paper reports on the Libraries' experience with the pilot project and the continuing end-user access program for faculty. Despite some reservations about the relative user-friendliness of the RLIN search system, the author enthusiastcally endorses the use of RLIN as an end-user database.  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

This study compares the results of subject searching in two online catalog systems, one system with authority control, the other without. Transaction logs from Library A (no authority control) were analyzed to identify searching patterns of users; 885 searches were attempted, 351 (39.7%) by subject. One hundred forty- two (40.6%) of these subject searches were unsuccessful. Identical searches were performed in a comparable library that had authority control, Library B. Terms identified in "see" references at Library B were searched in Library A. One hundred five (73.9%) of the searches that appeared to fail would have retrieved at least one, and usually many, records if a link had been provided between the term chosen by the user and the term used by the system.  相似文献

This observational study examined the strategies that music students used to locate scores and media items in an academic library's online public access catalog (OPAC). During a usability test, investigators tracked students' search strategies and behaviors, and measured their success in identifying appropriate items. Students experienced briefer, less complicated, and more successful queries for media items than for music scores (the latter of which they struggled to find and properly identify). Class standing, library catalog experience, and prior library instruction had no significant effect on positive outcomes. Searches for music scores were highly sensitive to variations in query wording, and students frequently struggled to revise their searches.  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

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

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

LIAS, the Pennsylvania State University's (Penn State) integrated interactive online system, provides for messaging by the user to inform library staff of errors found in bibliographic records. The message is sent by use of the OOPS command, and results in a printout which is used by processing staff for online catalog maintenance. This article describes LIAS, the use of the OOPS command, the processing of the resulting OOPS reports, an assessment of the effect of its use, and some speculation on the expansion of the LIAS message system for use in catalog maintenance.  相似文献

Reference staff at many libraries are facing a sudden and dramatic change in the size and composition of their library's online catalog as a result of loading large files of Government Printing Office (GPO) retrospective cataloging records. While these records provide a much-needed increase in access to federal documents, they have special characteristics which make them difficult to work with. This article is intended to provide reference librarians with the basic "GPO cataloging record literacy" they need to deal successfully with the load of these records into an online catalog, and also to explore some of the specific implications of such a load for reference service.  相似文献

This article discusses some of the lesser known complexities of LEXlS and WESTLAW and the necessity for evaluating these systems critically. Sample searches highlight the major differences between WESTLAW'S and LEXIS's search protocols. Comparable features of each system are examined to show how users can improve the qualily of their search results and to warn of unintended consequences when users misapply them. Strategies for formulating searches that retrieve relevant cases and prevent the exclusion of potentially relevant cases are considered, along with the economics of online searching. Although the searches presented are limited to Ohio case law, they are adaptable for exploring the nuances of online searching in other state and federal jurisdictions.  相似文献

Ways are explored in which public library children's librarians can help sighted children increase their understanding of persons with visual impairment and their skills in communicating with them. Interviews were conducted with six children's librarians and six BPH subregional librarians, and searches were made in the public library catalogs and the Regional BPH Library fiche catalog for selected titles. Three areas for discussion emerged: reader advisory and reference questions, collection development, and programming. Public library children's librarians and BPH subregional librarians can jointly coordinate provision of children's services by identifying and building on present strengths in collection development and programming.  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

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

Librarians at the Arnold Bernhard Library of Quinnipiac University were at a crossroads with electronic reference books. At first they had added the titles to the library's web page, generated records to individual titles in the online catalog, and even established links to their content using the link resolver in the online catalog. It was still felt that the collection was not living up to its potential. 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 – all of this done with no programming beyond basic HTML. Early usage reports beginning in the Fall of 2007 prove that the concept has found an audience.  相似文献

In 2009, the Technology Development Team at the New York-based Information Delivery Services (IDS) Project created IDS Search, a consortial catalog that promoted the group's collection and interlibrary loan features equally with the local collection and local availability. Because the success of IDS Search relied heavily on users fully understanding the different types of availability, the authors conducted usability studies to investigate how well users could determine how to locate materials and understand the availability of items. Eye-tracking analysis was used to determine how well users understood availability, related text, and meanings of terms. The studies found that users had difficulty navigating the functions of the online public access catalog (OPAC) and could not easily differentiate among items that were immediately available, available in a few days, or available online as a preview.  相似文献
