Some librarians embrace discovery tools while others refuse to use them. This lack of consensus can have consequences for student learning when there is inconsistent use, especially in large-scale instruction programs. The authors surveyed academic librarians whose institutions have a discovery tool and who teach information literacy classes in order to identify barriers to using them and to develop strategies to effectively integrate them into instruction. The authors used the survey results and recent studies on the research habits of undergraduates to propose strategies for integrating the discovery tool at the programmatic level in a more meaningful and sustainable way. 相似文献

Implementing discovery tools and getting them to work with existing library services often leaves very little time for their promotion and for the thoughtful, ongoing evaluation and curation of their content. However, the expectations and experiences that users have about discovery tools are often directly related to the content and the way that content is described. In our efforts to work with vendors to resolve the underlying business issues that prevent us from having all of the metadata for our resources included in our discovery tools, we may have lost sight of our role in curating and evaluating the usefulness of the content that is already included in them. 相似文献

ABSTRACTDiscovery tools are used in libraries to bring together books, articles, and other resources. Research has focused on user and librarian evaluation of these tools, but there are few evaluations of non-book and non-article sources. Discovery tools can also include metadata for local collections harvested through the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). Creating these harvests can be time consuming for staff, so it is important for libraries to understand if and how patrons use these records. The University of Nebraska-Lincoln Libraries (UNL Libraries) harvests metadata from local collections into the Encore discovery tool. A study was conducted to analyze patron use of OAI-harvested records. This study analyzed usage data for harvested collections obtained from different discovery sources and referrals through Encore. Google Analytics was used to evaluate searcher behavior differences between content referred through Encore and other referrals. Although discovery through Encore did not result in high numbers of traffic, there is evidence that patrons who discover records through Encore take more time looking through records than patrons using other discovery methods. This increase in time is a measure of engagement and may be reason enough for libraries to consider adding OAI-harvested collections to their discovery tool. 相似文献

Web-scale discovery systems are gaining momentum among academic libraries as libraries seek a means to provide their users with a one-stop searching experience. Illinois State University's Milner Library found itself in the unique position of having access to two distinct discovery products, EBSCO Discovery Service and Serials Solutions’ Summon. Two researchers at Milner conducted a usability study for the former product in 2010, and now two other researchers, including one involved with the EBSCO Discovery Service study, have conducted the same study on the latter product. The goals of the study were twofold: first, to identify user behavior while using discovery systems’ search features and to see whether using these features would improve the user's searching experience, and second, to compare user experiences with EBSCO Discovery Service and Summon at Illinois State University. The similarities and differences in user expectations, use, manipulation, and satisfaction with both discovery tools are explored in this article, with the ancillary hope that libraries investigating discovery tools might be able to make a more thoroughly informed choice in acquiring their own Web-scale discovery system. 相似文献

Discovery tools have been widely adopted by academic libraries, yet little information exists that connects common practices regarding discovery tool implementation, maintenance, assessment, and staffing with conventions for research and instruction. The authors surveyed heads of reference and instruction departments in research and land-grant university libraries. The survey results revealed common practices with discovery tools among academic libraries. This study also draws connections between operational, instructional, and assessment practices and perceptions that participants have of the success of their discovery tool. Participants who indicated successful implementation of their discovery tool hailed from institutions that made significant commitments to the operations, maintenance, and acceptance of their discovery tool. Participants who indicated an unsuccessful implementation, or who were unsure about the success of their implementation, did not make lasting commitments to the technical maintenance, operations, and acceptance of their discovery tool. 相似文献

Within the next few years, traditional online public access catalogs will be replaced by more robust and interconnected discovery layers that can serve as primary public interfaces to simultaneously search many separate collections of resources. Librarians have envisioned this type of discovery tool since the 1980s, and research shows that discovery layer functionality and features have already resolved, or will soon remedy, many of the known issues with the traditional online public access catalog. The authors of this article review the literature on discovery, focusing on the evolution from the traditional online public access catalog to newer discovery interfaces, and summarize what has been published regarding the selection and evaluation of these new tools. Based on this review, emerging trends in the acquisition of discovery layers are described, including: the amount of time libraries devote to selection and evaluation, the staff involved and their areas of expertise, which discovery tools were selected to review, the evaluation methods used, and the features and functionality evaluated. The authors conclude with a discussion of the opportunities and concerns for libraries and their patrons related to discovery efforts, and provide direction for future research. While discovery layers are still developing, they show great promise in increasing the use and usability of library resources. 相似文献

AbstractAcademic libraries have increasingly adopted web-scale discovery tools in order to meet the expectations of students who want immediate results, efficient algorithms, and a single search box. As they have become the de facto search tool at many libraries, librarians and patrons alike have been forced to confront the way they think about research processes and in some cases, modulate ingrained habits. In this article, the authors explore student perceptions of efficacy, relevancy, and ease of use of a library discovery tool through a 2017 mixed-methods user experience study conducted at three City University of New York (CUNY) campuses. The results from this user study will be useful to other institutions that already have implemented discovery layers within their library and help inform website design, discovery layer design, and pedagogy. By combining student interviews with a task analysis, the authors were able to learn more about student search behaviors, how they respond to challenges, and what they expect from search tools. Identifying these barriers to student use of the Primo discovery tool has helped us articulate best practices for instruction and interface customization that may address these barriers and has illuminated implications for website integration. 相似文献

Academic libraries offer a variety of tools for students to find information, including discovery systems and traditional library databases. This study contributes to the growing body of knowledge on student information-seeking behaviors by comparing how upper-level students majoring in Social and Behavioral Sciences use these two categories of search tools. Student search behavior and the use of search features, facets in particular, are quantified for each tool. The authors explore with statistical analyses whether these practices aid or hinder students in their search for high quality information. Qualitative data from student interviews is selectively employed to aid in explaining the results. Key findings include the differential use of search features in the discovery system versus the traditional database, and the relationships between the use of certain facets and the quality of sources chosen by students. Implications for instruction, search interface configuration, and default settings are discussed. 相似文献

ABSTRACTLibraries face many challenges in making electronic resources accessible and discoverable. In particular, the exponentially incre-asing number of licensed and open access electronic resources and the dynamic nature of consortial collections (platform changes, title transference between packages, and package overlap) present challenges for cataloging and discovery. From March 21 to April 10, 2017, the authors performed a selected review of library literature and conducted a survey of library consortia worldwide to ascertain the cataloging models, strategies, and advanced technological tools used to ensure discovery of consortial collections. The findings from the literature review and survey are summarized in this article. 相似文献
