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 article outlines a methodology to generate a list of local core journal titles by doing a citation analysis and details the process for retrieving and downloading data from Scopus. It analyzes correlations among citation count, journal rankings, and journal usage. The results of this study reveal significant correlations between journal rankings and journal usage. No correlation with citation count has been found. Limitations and implications for collection development and outreach are also discussed. 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
