Since the early days of e-resource management, holdings maintenance for electronic resources has been a very time consuming and manual process. While the emergence of electronic resource management systems (ERMS) has improved this process to a significant extent, holdings maintenance tasks remain labor intensive due to the increased volume of electronic content to manage, as well as issues related to metadata quality. To ameliorate many of the problems associated with managing electronic resources, and in recognition of a need for greater accuracy and efficiency, some knowledgebase providers are beginning to offer libraries options to automate holdings maintenance for electronic resources. In 2014, OCLC developed a service to provide automated holdings management for a select group of content providers. Within the WorldCat knowledge base system, library specific holdings for e-book and e-serial collections can be managed within the knowledge base without the need for library staff to manually intervene. At the University of Toronto Libraries, we decided to take OCLC's automated holdings management service for a test-drive. For three vendor packages, we conducted an on-going comparison between the library's holdings list and the title listing supplied by the automated service. This presentation will outline the results of this investigation, highlighting the benefits and drawbacks of automated holdings maintenance. The talk will also provide a vision of what the automated holdings management service could look like in the future. Speaker: Marlene van Ballegooie, Metadata Librarian, University of Toronto
