E-books and audiobooks are becoming increasingly popular in the United States. Unfortunately, the supply of digital titles does not meet the demand. Library patrons must frequently wait for weeks to receive popular e-books. We examined the issue of wait time for e-book and audiobook titles using three public library patron accounts to gather data consisting of the average daily number of wait spots for each title, and days until the title was available. Based on our observations, we propose the Waiting Reduction Rate (WRR) formula to determine the average number of wait spots per title as a metric to help determine a better holds-to-copy ratio for electronic materials and reduce patron wait time. 相似文献

EXCEL在角度转换中存在的问题及解决的方法 总被引:1,自引:0,他引:1
EXCEL在工程领域应用广泛,但它在角度不同单位间的转换过程中,当以度分秒为单位的角度值的秒位数为零转换成以度为单位的数值时,会出现较大的误差,甚至达 38″或-61″。对于严密工程如精密机器安装定位、公路铁路等地下隧洞控制测量及贯通等,这个误差的影响会造成比较严重的后果。提出了角度不同单位间的转换公式,同时也分析了出错的原因和解决的办法。 相似文献

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
