Michael Levine-Clark presented on demand-driven acquisition (DDA) as a strategy for building monographic collections. He discussed how DDA allows libraries to provide access to a much larger collection by only paying for content that is used, matching acquisitions to immediate demand. The University of Denver implemented a DDA program through EBL in 2010 that has expanded access while spending less than traditional purchasing models. DDA provides both challenges and opportunities for managing the consideration pool and defining the long-term collection.
