Print Book vs. DDA Ebook Acquisition and Use at KSU Library

摘要

In January 2012, Kent State University Libraries implemented a 6-month pilot project for a Demand Driven Acquisitions (DDA) ebook purchasing model that uses a combination of the acquisition services provided by our primary book jobber (YBP) and the access services provided by an Ebook distributer (eBrary). Using the book jobber mediated DDA model provided the library with selected discovery records that closely matched specifications of the library’s print approval plan. The initial record load for DDA eligible records consisted of about 22,000 ebook records. New discovery records were added to the catalog each week as new eBrary ebooks became available.ududThis presentation will report our assessment of this new acquisition model as compared to that of print books in terms of budget, costs, workflow, subjects, publishers, and publication dates. Because DDA empowers library users to choose which ebooks are actually purchased based on actual use, our assessment also compares ebook usage from a DDA discovery pool with print book circulation of an equivalent amount of latest acquisitions. The results of this study will help answer some of the key questions about this new acquisition model: (1) Does DDA align the library’s collection with current user requirements? (2) Does DDA lead to more active use of library book collection? (3) Is DDA cost-effective as an acquisition model? (4) What issues are associated with DDA and how may these issues be addressed?
