This poster discusses Demand-Driven Acquisitions (DDA) of e-books at UNT.

Physical Description

2 p.


In 2012, the University of North Texas (UNT) launched a new strategic plan based on Four Bold Goals, one of which is to become a leader in operational effectiveness. During this same period, the UNT Libraries embarked on a pilot of patron- or demand-driven acquisitions of electronic books. Because little was known about how the e-books would be used, the Libraries chose the service model that enabled the purchase of all titles that met the trigger thresholds. Midway through the pilot, the authors examined the usage of purchased titles to determine if other purchasing models would have been more efficient and effective use of funds, in line with that institutional goal. The authors applied the usage data from the first six months of the program to each of three purchasing scenarios. The poster will visually demonstrate the differences of these scenarios, explain the steps involved, and present the conclusions and decisions that were made based on the results. Librarians who manage similar PDA programs will be able to use information to analyze their own collections, while those who are considering such programs will also be able to consider the results in determining the purchasing model most relevant to their patrons' needs.
