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

Public library systems' websites were often the sole means for older patrons to access library services and programming during the COVID-19 pandemic. This study integrated Pauwels' (2012) framework to analyze 25 Ontario public library systems' websites for evidence of their available programming for older adults during the early months of COVID-19. The 640 identified programs for older adults revealed a number of patterns, including issues regarding visibility and representation of older patrons on library websites as well as assumptions surrounding older adults' access to technologies. Discussions consider three implications for public libraries as they reopen and create new virtual spaces “postpandemic”: questioning (re)distributions of resources that support both virtual and in-person services, questioning implicit assumptions that digital connection will foster social connection, and questioning the effects of the library as a virtual space on feelings of social connectedness.  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 MELVYL MEDLINE project resulted in the addition of a full five-year subset of MEDLINE to the University of California's (UC) MELVYL online union catalog. As one of the nation's largest MEDLINE end-user searching systems, MELVYL MEDLINE provides online bibliographic access to the biomedical journal literature for all UC personnel at over seventy library sites or by remote access. This paper summarizes the project's accomplishments, reports MELVYL MEDLINE use and its impact on library services, and provides insights for other end-user search systems. The project serves as a model for adding databases to the MELVYL catalog and demonstrates the potential for use by other disciplines of a specialized database when readily accessible. Evaluation results report high user satisfaction and high usage. However, many advanced searching features of the interface are little used by searchers. Effects on library services include marked increases in reference transactions and interlibrary loans, with significant declines in mediated search services. Future MELVYL MEDLINE enhancements include matching search retrievals to journal locations, linkage to an online document delivery system, and consideration of building a superset of databases by combining MELVYL MEDLINE with citations from another database in the MELVYL 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

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

Abstract

This study examines the promotion and knowledge of online patent literature search among students, librarians, and instructors to enhance university scientific output in Zanzibar. The study was guided by four key questions: What is the level of awareness of students, instructors and library staff about patent documents as source of information? To what extent do students and instructors access online patent databases? What is the library experience in training students about online patent literature searching?, and what are the challenges facing library and instructors in promoting patent literature search? The study used survey approach whereby questionnaire and interview were used to collect data. The recent literatures regarding online patent literature searching were also critically reviewed. A survey was conducted at two Universities in Zanzibar namely the State University of Zanzibar and Zanzibar University, whereby 20 library staff, 10 instructors and 140 undergraduate students from the School of Computing and the Faculty of Engineering were involved in this study. The findings show that more than three quarters of respondents were either partially aware or not aware at all about the existence of free online patent databases. Likewise, the majority of students had no enough skills of patent literature searching. However, usually the library organizes training on general online literature searching skills but patent literature searching was not effectively taught and a big challenge observed in this study regarding promotion of patent literature searching is inadequate patent searching skills among library and instructors. Based on the findings, the study proposed several recommendations to rectify the existing problem.  相似文献

Although not much has been written about older adults' use of academic libraries, they experience challenges navigating these considerable physical and online library spaces. Members of a university lifelong learning community were recruited for a 10-week diary study. They were asked to record their real-time information seeking behaviors related to their study groups, and the challenges they faced looking for or using information. They were also asked to rate their enjoyment to determine whether the joy of engaging in community learning extends to the information seeking process. Findings from sixteen diarists show that they sought information primarily on a specific topic, person, or book. They used a variety of resources but found books and periodicals most useful. They struggled with trust, technology, time management, library anxiety, information overload and dissemination. With increased understanding, librarians can be better equipped to reach older adults that are doing scholarly research and contribute to their success.  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

A traditional library catalog does not do justice to maps and aerial photographs. Text can never fully describe them and maps' and aerial photographs' geographic coverage or perimeters cannot be displayed visually in the online public access catalog (OPAC), so searching based on their textual metadata without specific spatial reference data used also for display purposes is often not enough to locate relevant items. The Hebrew University of Jerusalem's (HUJI) Geography Department has developed a spatial search engine for their scanned aerial photographs collection that allows users to locate one or more aerial photographs according to the area of the Earth's surface that was photographed and their accompanying metadata. The Humanities and Social Sciences Library, which holds a large unscanned print map collection, has asked to integrate a similar map search mechanism in the Department's existing search engine, and a new website was launched in December 2015 (http://ccg.huji.ac.il/aerialphotos/) showing the aerial photographs' center points alongside the maps' rectangle perimeter. The search engine retrieves maps and aerial photographs that intersect with a user-drawn rectangle. This article discusses the characteristics of these collections, the rationale behind searching for maps and aerial photographs together, and the process of defining and building this spatial search engine. This method allows users to view which items are available in their area of interest side-by-side, on a Google Maps background map.  相似文献

General Social Survey data were used to test the claims that (a) older adults watch more television than younger adults and (b) they do so because of poor health, retirement, and widowhood. Older adults did watch more television on average than other age groups. This effect was not explained by birth cohort or altered by time of measurement. However, the age effect was small (despite striking mean differences), because variability within the youngest and oldest groups was large. Overall, traditional explanations of older adults' viewing were largely unsupported. Demographic and social variables explained younger adults' viewing better than older adults'.  相似文献

The serials catalog is a key link in the search process for current information in a library. Decades of evolution in the ways of entering serials in the catalog have compromised the usability of this important research tool. This article examines (1) the results of studies on serials catalog use; (2) the reasons for serial search failures; (3 the cataloging rules and practices researchers need to understand in order to effectively use a serials catalog; and (4) the local in-house modifications which often complicate the search process. It also offers searching hints which will help reference personnel improve their ability to successfully locate serial entries for library patrons.  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

The Internet has provided OCLC with another delivery mechanism to support its chartered public purpose of ex- access to the world's information and reducing rising information costs. This network of networks has helped OCLC and its member libraries reach electronically a new audience of end users with new products and new technologies designed especially for them. OCLC offers three reference products via the Internet: The First - Search Catalog, the EPIC service, and The Online Journal of Current Clinical Trials. All can be accessed using the Internet from an enduser's home, office, dorm room, laboratory, hotel room-or any other location with a modem nearby-as well as from a library. FirstSearch is a new online information service designed for library patrons, with an end-user interface that allows patrons to move through the online search process in just a few simple steps, without special training or online searching experience. The EPIC service is an online information service with a command interface designed for the advanced searcher. Both of these services offer access to a number of databases, including the OCLC Online Union Catalog, an electronic card catalog of 28 million records used by more than 16,000 libraries.  相似文献

Summary

Digital reference is an important research area with the potential to enhance information delivery to library patrons. The process of digital reference involves the challenges and problems of an interactive computer-mediated reference interview. Related studies of mediated online searching have identified the major tasks during a mediated online search. The search intermediary's tasks included gathering information on the information need, previous searches on the topic by the information seeker, search terms and strategies, database selection, search procedures, system's outputs and relevance of retrieved items, and the number of topics to be searched. The information seeker's tasks include providing information to the search intermediary on their topic, discussing their previous information seeking and evaluating the online search output. Models of digital reference interviews need to include more complex information seeking behaviors, such as successive searching and multitasking. Further research is needed to extend our understanding of digital reference processes.  相似文献

Active use of information and the media may promote healthy aging. The everyday information behavior of older adults' is examined, and the activating role of the media thereon—that is, the use of television, radio, newspapers, magazines, and the Internet. Enactment, an evidence-based concept, is introduced as a theoretical tool that refers to the phenomenon of information and media use leading to action in concrete daily activities. The research strategy was qualitative, consisting of content analysis of semi-structured interviews of 13 retired teachers and the media diaries of 306 older adult Finns. Fifteen categories of information and media use were proposed and grouped into four forms of enactment on the basis of their temporal nature, namely, direct or indirect engagement: 1) general routines and housework, 2) healthy lifestyle, 3) cognitive tasks, and 4) interaction with others. Enactment takes place when older adults' everyday information behavior leads to observable actions, such as organizing their daily activities, preparing food, exercising and engaging in healthy activities, practicing language skills, or filling in crossword puzzles. These findings support the notion that use of information and the media can motivate older adults to stay active in life. Therefore, the concept of enactment may prove useful in gaining a better understanding of certain physical, cognitive, and social aspects of everyday information behavior and their impact on people's well-being. However, the findings should be validated in a broader population.  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

This article reports on the results of a study that examined public library website adherence to senior-friendly website guidelines. A total of 104 public library websites (N = 104) were analyzed. Compliance with Internet design accessibility principles recommended for older adult Internet users was analyzed, and the findings suggest that current public library website practices may be problematic. As a result, public library websites offering resources and services may present potential accessibility challenges to older adults. Recommendations relevant to public libraries for enhancing library websites and online content are presented.  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
