Are We There Yet? Calculating Wait Time for Popular Digital Titles

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.

基于“问题-用户”的网络问答社区专家发现方法研究

[目的/意义] 以网络问答社区为研究对象,提出基于“问题-用户”传播网络的专家发现方法,为建立用户激励机制、完善专家推荐方法提供借鉴。[方法/过程] 通过分析开放问答模式的特点,以“问题”和“用户”为节点、“答题关系”为有向边,构建“问题-用户”权威值传播网络,利用答案质量改进加权的HITS算法。[结果/结论] 提出的算法可以较好地兼顾用户的答题数量与答案质量,能够选择出活跃度高、知识渊博的用户作为专家。     

Re-Envisioning E-Resource Holdings Management

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.
