Abstract
Researchers at Kent State University Libraries have collected DDA (demand-driven acquisition) e-book program data from eight large academic libraries in order to further research on DDA use and efficacy. As libraries transition more and more to the just-in-time acquisition model, it is even more imperative to understand the factors that contribute to successful collection management practices and sustainability. With multiple years of data from eight institutions, this will be the first large-scale study of this kind. In this study DDA e-book data was examined from each institution that detailed order and license information, bibliographic data, and usage data for each program. All institutions used ProQuest as their e-book provider and YBP as the DDA e-book jobber. A survey was also used to gather information about the parameters of each DDA discovery pool program variables. Formula logic based on actual usage data was developed in order to have an apples-to-apples comparison of overall cost under various DDA model scenarios. This study offers perspectives and considerations for implementing and evaluating a DDA program in large academic libraries. It also analyzes DDA e-book program commonalities and future directions that help librarians in choosing the e-book DDA business model that works best for their library.
