ABSTRACT The Council on Public Liberal Arts Colleges (COPLAC) libraries websites were assessed for Section 508 errors using the online WebXACT tool. Only three of the twenty-one institutions (14%) had zero accessibility errors. Eighty-six percent of the COPLAC institutions had an average of 1.24 errors. Section 508 compliance is required for institutions receiving federal funding. While this study shows the need to correct the existing errors, the low error rate shows that COPLAC institutions have generally been conscious of accessibility standards and are working toward achieving fully accessible websites. Studies of the connections between average accessibility errors and the geographic locations of these institutions, the amount of federal funding received, and size were inconclusive. The main aim of the study is to demonstrate the need to check library websites using the free WebXACT tool. This tool offers suggestions for accessibility that should serve to decrease the number of pages that are inaccessible to patrons. 相似文献

Abstract Library Web pages are increasingly designed to be the initial entry point for research, whether used from the library or off campus. But the pages must be intuitive and easy to use or students may bypass them completely, in favor of more familiar Web resources. This article presents the process, results, and evaluation of a Web usability study conducted at Linfield College with undergraduate participants. Web usability testing was a relatively quick and inexpensive way to find out how students used the library Web pages, information that proved invaluable in making effective modifications to them. In the process, researchers gained insights into student online searching and research patterns that have informed reference and teaching activities as well. 相似文献

ABSTRACT Virtual reference using chat or instant messaging clients (IM) has become an expected service offering for libraries seeking to cater to today's Web 2.0 patrons. The use of chat aggregators to monitor multiple accounts in one interface allows libraries to reach a wider audience of IM/chat users. Embedding chat widgets into library Web pages can further increase chat reference use because it allows patrons without IM/chat experience or accounts to reach librarians seamlessly. This article reviews the use of aggregator software for chat reference monitoring, examines the popularity of the MeeboMe! chat widget for embedded virtual reference and briefly describes the experiences and recommendations of librarians at Samford University Library as they have implemented its use. 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

ABSTRACT. This study is the first to investigate the amount and type of information about children's services described in Japanese public library websites, with particular reference to the Web pages intended for children, and the extent to which usability is taken into account in the design of these websites. Further, the study analyzes what kinds of content are more prevalent in children's services as described in Japanese public library websites in comparison with the actual delivery of these services. Finally, the study considers the usability of children's Web pages from the perspectives of how easy they are to read and understand. 相似文献

Web search algorithms that rank Web pages by examining the link structure of the Web are attractive from both theoretical and practical aspects. Todays prevailing link-based ranking algorithms rank Web pages by using the dominant eigenvector of certain matrices—like the co-citation matrix or variations thereof. Recent analyses of ranking algorithms have focused attention on the case where the corresponding matrices are irreducible, thus avoiding singularities of reducible matrices. Consequently, rank analysis has been concentrated on authority connected graphs, which are graphs whose co-citation matrix is irreducible (after deleting zero rows and columns). Such graphs conceptually correspond to thematically related collections, in which most pages pertain to a single, dominant topic of interest.A link-based search algorithm A is rank-stable if minor changes in the link structure of the input graph, which is usually a subgraph of the Web, do not affect the ranking it produces; algorithms A,B are rank-similar if they produce similar rankings. These concepts were introduced and studied recently for various existing search algorithms.This paper studies the rank-stability and rank-similarity of three link-based ranking algorithms—PageRank, HITS and SALSA—in authority connected graphs. For this class of graphs, we show that neither HITS nor PageRank is rank stable. We then show that HITS and PageRank are not rank similar on this class, nor is any of them rank similar to SALSA.This research was supported by the Fund for the Promotion of Research at the Technion, and by the Barnard Elkin Chair in Computer Science. 相似文献

ABSTRACTThis case study reviews the responsive Web design project undertaken by the Library, Institute of Technology Tallaght, with Granite Digital, including the preparatory literature review, the design process, task allocation, and the technologies leveraged to deliver the final design. The library is a small academic library with limited resources, and the project took place during a particularly challenging period in Ireland. The different types of testing the site underwent before launch are discussed, including testing of the design itself across browsers, accessibility testing using free online resources, testing the responsive design using free online resources, and physical device testing. The article outlines how feedback was gathered and addressed, and discusses plans for future upkeep and development. Finally, the article concludes that it is possible for a small academic library to successfully deliver a high quality library Web site using responsive design. 相似文献

Abstract Despite major, ongoing changes in the profession and in library school curricula, the basic principles of librarianship can and should always be applied, regardless of medium or situation. However, patrons have changed the ways they prefer to search for and access information. This means that librarians must both update their understanding of these principles and find ways to apply them more proactively. One effective response is to design and market library Web pages as preferred gateways to electronic information and instruction. Librarians can transform Web pages into “one-stop-shopping information portals” for users, providing not only information, but also instruction in how to find and evaluate information. Applying Ranganathan's Five Laws of Library Science to Web page designis a useful way to determine iflibrarians are providing the kind of Web pages their patrons need. 相似文献

ABSTRACT A year ago, West Chester University Libraries began using the LibGuides library content management system. In the 1st year since implementing LibGuides (http://subjectguides.wcupa.edu/), our subject librarians have developed numerous subject guides, replacing outmoded and outdated Web pages with new guides that have a more appealing format. We have also found that Web guides can be used for projects beyond the traditional library subject guide. One of the best features of the LibGuides software is that it allows our subject librarians to easily repackage information and resources in multiple ways that suit different audiences. In this article, the authors describe how they have used these guides to respond to the needs of their university community and how they hope to expand the potential uses of the Web guides. 相似文献

ABSTRACT As the World Wide Web has advanced since its inception, librarians have endeavored to keep pace with this progress in the design of their library Web pages. User recommendations collected from focus groups and usability testing have indicated that the University of Scranton's Weinberg Memorial Library's Web site was not working as intended, and the library's home page, in particular, was cluttered. Focus groups indicated that the process of accessing the library's databases from off-campus took too many steps, key resources were not located in key areas of the page, links were too close together, and the font was too small. Library staff determined it was necessary to rethink and redesign its pages. Self-reports from focus groups were insufficient to get at the mechanics of Web page use. Through usability testing, librarians were able to observe students and faculty completing simple research and directional tasks. Before “going live” with the new page in January 2007, users who had participated in the focus groups and in the usability testing were surveyed about the redesigned library Web page. The users indicated that the new Web page was less confusing, easier to use, and somewhat more intuitive than the previous library Web page. Web sites are always works in progress, and academic librarians should be proactive about making changes to their library Web sites to take advantage of emerging technology and to meet user expectations. 相似文献

PurposeThis study analyze academic library services during Covid-19 pandemic (2020 and 2021), as well as the challenges they face, emerging library roles, and the most effective communication tools.MethodA systematic review of the relevant literature was undertaken following PRISMA guidelines. The relevant literature was retrieved from four major scholarly databases (Scopus, Web of Science, Library, Information Science & Technology Abstracts (LISTA), and Library and Information Science Abstracts (LISA)). The relevant 23 studies were included fulfilling inclusion criteria. A quality assessment of the included studies was also performed.FindingsThe findings revealed that Covid-19 pandemic is certainly effecting and transforming libraries, their services and management. The library services during Covid-19 pandemic, their fundamental challenges, emerging roles, and available preferable communications tools are the categories in this study to better understand the pandemic-transformation.ImplicationsThe practical and policy implications are that libraries must establish infrastructure and improve accessibility in order to provide the best possible support to modern library users who access resources remotely in this rapidly evolving digital environment. Organizational policymakers and library directors should prepare emergency and disaster management plans. The libraries should ensure their presence on social media and make use of their library websites. 相似文献

In 2007, public librarian Dave Pardue launched Slam the Boards!, a monthly call for librarians to enter online answer boards such as Yahoo! Answers and answer questions, announcing to the public that they are librarians. Graduate library and information students participated in this required assignment in a basic reference class. Students reported that this experience caused them to reflect on guiding reference documents and their own career plans as they gained confidence in engaging in remote reference service. Recommendations for future involvement calls for in-class demonstration of answer boards, rehearsal, and monitoring of answer boards. 相似文献

Abstract Creating Web research guides is an effective way to distribute the research expertise and resource knowledge of reference librarians. Using a Web reference guide for Pittsburgh history resources, the author demonstrates that reference librarians can play an integral role not only in the promotion of community resources, but also in the teaching and research of local history. Examples of the Web pages are included, as well as the rationale for the arrangement and inclusion of particular resources and research tips. 相似文献

Abstract Access to biological information on the World Wide Web continues to grow at a rapid pace. Many resources that previously required a trip to the library are now accessible from the desktop PC. Three major categories of biology Web sites are explored: those with citation information, those functioning as clearinghouses or directories to other Web sites, and those that present biological information in innovative ways. The suggested Web sites are some of the best and may serve as models for future Web development. Many useful citation Web sites are fee-based and are likely to continue as such for the near future; MEDLINE and AGRICOLA are important exceptions. Many significant clearinghouse and information Web sites are not fee-based and allow innovative ways of finding and sharing information. The state of research information on the WWW is not developed enough for the researcher to forego using paper sources. 相似文献

Online display advertising is a multi-billion dollar industry where advertisers promote their products to users by having publishers display their advertisements on popular Web pages. An important problem in online advertising is how to forecast the number of user visits for a Web page during a particular period of time. Prior research addressed the problem by using traditional time-series forecasting techniques on historical data of user visits; (e.g., via a single regression model built for forecasting based on historical data for all Web pages) and did not fully explore the fact that different types of Web pages and different time stamps have different patterns of user visits. In this paper, we propose a series of probabilistic latent class models to automatically learn the underlying user visit patterns among multiple Web pages and multiple time stamps. The last (and the most effective) proposed model identifies latent groups/classes of (i) Web pages and (ii) time stamps with similar user visit patterns, and learns a specialized forecast model for each latent Web page and time stamp class. Compared with a single regression model as well as several other baselines, the proposed latent class model approach has the capability of differentiating the importance of different types of information across different classes of Web pages and time stamps, and therefore has much better modeling flexibility. An extensive set of experiments along with detailed analysis carried out on real-world data from Yahoo! demonstrates the advantage of the proposed latent class models in forecasting online user visits in online display advertising. 相似文献
