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

This study investigates distance learners' information literacy skills in using digital library resources and the factors (online learning and information manipulation) that correlate with learners' information seeking self-efficacy. In addition, distance learners' preferences with regard to digital resources selection and interests of developing information seeking skills were examined. 3517 students enrolled in one or more distance education courses were invited to participate in the online survey; 219 students completed the survey, for a response rate of 6.2%. The results revealed that distance learners who have higher self-efficacy for information seeking and proficiency in information manipulation exhibited higher self-efficacy for online learning. Moreover, students with high self-efficacy demonstrated superior knowledge of digital resources selection. Students who have low self-efficacy with regard to information seeking were more likely to express interest in learning how to use the library resources, although learning techniques for database searching was the exception.  相似文献

Background:Few electronic resources are available for new mothers with concerns about changes in their pelvic floor following childbirth. Patients may struggle when seeking authoritative information regarding pelvic floor conditions online given the sensitivity of the topic as well as the inadvertent connection to obscene or demeaning content found online. A health sciences librarian partnered with the Motherhood and Pelvic Health Study, an interdisciplinary research group, to provide expert searching skills for a particularly challenging health condition that patients struggle to find useful information on.Case Presentation:A custom rubric was developed to evaluate existing information products, which included criteria for cultural sensitivity, conflicts of interest, and other red flags. This evaluation process enabled the research team to identify top-tier evidence-based materials that were culturally congruent. This collaborative evaluation process led to the creation of a web-based toolkit resource for new mothers concerned about changes in their pelvic floor. The toolkit connects women to pertinent information on a national health organization''s patient portal, supplemented by videos created by the team to serve as models of communication for women and health care providers.Conclusion:When developing a web-based resource, health sciences libraries can partner with research teams to find, evaluate, and disseminate information. Culturally congruent toolkits such as this one can improve access to health information and lead to improved health outcomes. To ensure that the information highlighted in toolkits is both culturally congruent and authoritative, research teams should form advisory committees and partner with relevant professional medical associations.  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

This paper is based on Rachel Butler's dissertation carried out at the University of Sheffield as part of the MA Library and Information Services Management. The study examines people's online health information seeking skills, with the specific aim to identify how libraries and health services can work together in supporting digital and health literacy. A survey approach is used to explore online searching habits as well as librarian and health professionals’ views on health literacy. The key findings indicate that whilst the majority of respondents consider themselves to be health literate, there was an overall agreement that effective education and support could be achieved through the collaboration between libraries and health services, and specifically to signpost information and to provide targeted education. The limitations of the research for dissertation are recognised leading to recommendations that further study focuses on the impact of signposting and education on health literacy.F.J.  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

Indiana University School of Medicine Library (IUSML) has traditionally been a high volume searching institution. The dramatic effect of CD-ROM on online end-user searching and the negligible effect on mediated searching was reported in an earlier study. This follow-up study reveals that the proportion of mediated searching has been drastically reduced from 94% in 1986/87 to 39% as of November 1989. Mediated searches are declining in absolute numbers as well. End-user searching, by contrast, has increased by 54% percent over the previous year. A related trend is the increased use of CD-ROM by the librarian as an alternative to mediated online searching. These trends are expected to continue as IUSML expands its CD-ROM operation to include other databases. As mediated searching declines, the librarian's role will increasingly include end-user training.  相似文献

Background: Reviews of how doctors and nurses search for online information are relatively rare, particularly where research examines how they decide whether to use Internet‐based resources. Original research into their online searching behaviour is also rare, particularly in real world clinical settings. as is original research into their online searching behaviour. This review collates some of the existing evidence, from 1995 to 2009. Objectives: To establish whether there are any significant differences in the ways and reasons why doctors and nurses seek out online information; to establish how nurses and doctors locate information online; to establish whether any conclusions can be drawn from the existing evidence that might assist health and medical libraries in supporting users. Methods: An initial scoping literature search was carried out on PubMed and CINAHL to identify existing reviews of the subject area and relevant original research between 1995 and 2009. Following refinement, further searches were carried out on Embase (Ovid), LISA and LISTA. Following the initial scoping search, two journals were identified as particularly relevant for further table of contents searching. Articles were exclused where the main focus was on patients searching for information or where the focus was the evaluation of online‐based educational software or tutorials. Articles were included if they were review or meta‐analysis articles, where they reported original research, and where the primary focus of the online search was for participants’ ongoing Continuing Professional Development (CPD). The relevant articles are outlined, with details of numbers of participants, response rates, and the user groups. Results: There appear to be no significant differences between the reasons why doctors and nurses seek online Internet‐based evidence, or the ways in which they locate that evidence. Reasons for searching for information online are broadly the same: primarily patient care and CPD (Continuing Professional Development). The perceived barriers to accessing online information are the same in both groups. There is a lack of awareness of the library as a potential online information enabler. Conclusions: Libraries need to examine their policy and practice to ensure that they facilitate access to online evidence‐based information, particularly where users are geographically remote or based in the community rather than in a hospital setting. Librarians also need to take into account the fact that medical professionals on duty may not be able to take advantage of the academic model of online information research. Further research is recommended into the difference between the idealised academic model of searching and real world practicalities; and how other user groups search, for example patients.  相似文献

This article summarizes the author's dissertation regarding search strategies of millennial undergraduate students in Web and library online information retrieval systems. Millennials bring a unique set of search characteristics and strategies to their research since they have never known a world without the Web. Through the use of search engines, they have come to expect that searches can be completed using an easy, single search box that produces complete articles on just about any topic. However, the reliability and quality of much of the information on the Web is questionable. Conversely, information that resides in library information retrieval systems is often of high scholarly content, but there is not a single, user-friendly system for millennials to use. A case study investigation was conducted at the State University of New York at Oswego, a public undergraduate university in Central New York. The goal of the study was to identify the search strategies of a sampling of millennial undergraduate students in both Web information retrieval systems and library information retrieval systems in order to expand upon existing theories about millennials and to suggest interface design enhancements, which could make online library information retrieval systems easier for millennials to use. The findings recommend improving database search functionality, such as natural-language searching, spell-checking, and uniform full-text wording and placement. Results also suggested that increasing the availability of full-text articles would contribute to millennials’ use of library information retrieval systems.  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

BackgroundDuring the COVID-19 pandemic, students have trouble coping with the available health information regarding the coronavirus in their daily lives because of misinformation.ObjectivesThe aim of this study was to evaluate online health information seeking and digital health literacy among information and learning resources undergraduate students at Taibah University during the COVID-19 pandemic.MethodsTo investigate the primary goal, this study used a simultaneous exploratory mixed methods design. Seventeen students participated in phone interviews, and 306 were invited to complete an online survey.AnalysisThe collected data was analyzed using both quantitative (SPSS) and qualitative (NVivo 10) methods.ResultsSearch engines, social media, and YouTube were most often used by the respondents as sources to search for COVID-19-related information. COVID-19 symptoms, restrictions, and the current spread of COVID-19 were the most searched topics by the respondents. Significant and relevant differences emerged for the digital health literacy subscales “information search” and “adding self-generated content”. However, there were no significant differences in the digital health literacy subscale “determining relevance”.ConclusionUsing the internet to provide health information tailored to the needs and interests of students to seek health information online and thereby improve their health literacy.  相似文献

Abstract

The researchers conducted a task-based usability test of the effectiveness of online research beginning on the library Web site homepage. The participants included five university faculty members, six graduate students, and six undergraduate students. All participants reported feeling satisfied with their overall research experience, though most were unable to effectively complete all the research tasks of the test. The researchers identified weaknesses in the approach and process of many participants, and overall usability issues of the library discovery tool and other library Web site pages and research interfaces. Findings indicate the need to strategically incorporate self-service information literacy and research skills help into the library Web site, and to implement navigation and design changes to the library homepage, discovery tool interface, online catalog, and across all the library's Web services.  相似文献

Googlitis, the overreliance on search engines for research and the resulting development of poor searching skills, is a recognized problem among today's students. Google is not an effective research tool because, in addition to encouraging keyword searching at the expense of more powerful subject searching, it only accesses the Surface Web and is driven by advertising. American higher education unwittingly fosters the use of search engines in research by emphasizing results rather than process. Academic librarians emulate teaching faculty in their reliance on lectures, and their course-related instruction is limited in its effectiveness because it is constrained to one-shot, lecture-driven sessions. A more effective way to teach research is to collaborate with faculty via problem-based and project-oriented learning tasks that incorporate authentic discipline-specific information finding and critical thinking into assignments.  相似文献

As new venues of information and tools for information access are emerging, people's online information seeking behavior is dramatically evolving. While a majority of well-established and classical models of information seeking and behavior are still valid, there is a growing need to study and explain novel information sources and information seeking behaviors that are unique to these sources. One emerging domain is social question and answer (Q&A). This article develops a research agenda for social Q&A, reviewing recent studies and identifying core issues, questions, and challenges.  相似文献

ABSTRACT

The article offers a model for library-centered undergraduate engagement with digital scholarship based on two years of successful implementation at Lafayette College. Librarians designed a competitive six-week summer internship where undergraduate students built their own digital research projects. Through their original projects, students practiced traditional research methods and simultaneously explored subfields of digital scholarship. The article's topics include the relationship between digital scholarship and information literacy, the library's role in facilitating digital scholarship, and the internship's design and execution. The article also includes reflections and recommendations for sustainable implementation.  相似文献
