For e-resource librarians, maintaining e-book and e-journal holdings within electronic resource management systems is a labor intensive and often manual process. In 2014, with the aim of saving library staff valuable time and effort, the Online Computer Library Center, Inc. (OCLC) launched a service to provide automated holdings management within the WorldCat knowledgebase. For a select group of content providers, including some of the largest e-book aggregators, holdings information can be populated and updated automatically within the knowledgebase without intervention from library staff. At the University of Toronto Libraries, we conducted a study to assess the accuracy and efficiency of these automated holdings management services. This presentation outlines the results of the study and provides suggestions for further improvement to the current services offered.  相似文献

This session reported the findings of a comparative analysis of how e-books are represented across multiple platforms. In this session, the presenters shared the results of a study that examined how a sample of academic e-books are represented across different platforms. Topics of analysis included: the inclusion of various metadata, the visual presentation of e-book content, and variations in search results. This presentation also focused on the similarities and differences between e-book representation and what impact these various representations might have on users of academic e-books.  相似文献

On the surface, it might appear that libraries with different collections, staffing levels, and budgets would have to make use of different tools to address their e-resource management needs. However, in their review of electronic resources lifecycle work at North Carolina State University and Georgia Perimeter College, Tessa Minchew and Sofia Slutskaya discovered that this is not always the case. The presenters reviewed the electronic resources lifecycle and three distinct types of tools (content management systems/wikis, Microsoft Access, and Trello) that are being used in different ways to address different lifecycle-related tasks at each of their institutions.  相似文献

Over the past thirty years NASIG has evolved as a community, supporting the exchange of ideas regarding serials in the early days and more recently expanding into broader topics such as electronic resources and scholarly communications. Thirty years of NASIG conference programs, publications, workshops, and webinars will be evaluated to identify trends and understand the evolution of NASIG as an organization.  相似文献

The University of North Texas Libraries provide extensive online access to academic journals through major vendor databases. As illustrated by interlibrary loan borrowing requests for items held in our databases, patrons often have difficulty navigating the available resources. In this study, the Interlibrary Loan staff used data gathered from the ILLiad interlibrary loan management system to investigate why patrons request locally available materials. This study resulted in recommendations for the Libraries' linking strategies in EBSCOhost databases. Several user education needs were identified and communicated to the Libraries' Subject Liaisons.  相似文献
