DDA in Context: Defining a Comprehensive Ebook Acquisition Strategy in an Access-Driven World

Internet-based technology has birthed a variety of ebook acquisition modes that differ significantly in number of accessible titles per acquisition dollar. We review these acquisition modes and argue that it is crucial for libraries to define a well-reasoned, comprehensive acquisition strategy that represents their optimal mix of all six modes. Each library’s strategy should reflect its institutional priorities relative to five key factors (choice of content and quality, discount, ease of use, permanence, and cost predictability) and integrate three complementary tactics (relating to subscription, demand-driven acquisition, and ebook approval plans) rather than rejecting one or more acquisition modes on principle. The goal of each library’s strategy should be to maximize access while ensuring that library users are served as effectively as possible over time, as we proceed in search of a sustainable future for academic ebook publishing, in collaboration with our publisher and vendor partners
