abstract: Electronic book (e-book) acquisition models have evolved over the decades they have been available to library customers. This review leverages findings from scholarly literature to document the proliferation and evolution of e-book acquisitions models, their strengths and weaknesses in various contexts, and their role in the collection development strategies of academic libraries. From firm orders and subscription packages to demand-driven and evidence-based acquisitions, engagement with e-book acquisitions models varies considerably based on factors such as library budget and staffing, institutional curriculum and programs, consortial affiliations, support for textbook affordability initiatives, and COVID-19 pandemic responses. The findings from this literature review suggest multiple acquisition models are frequently used in combination; librarians closely monitor e-book expenditures and use, regularly modifying acquisitions parameters; and e-book strategy is dependent on institutional goals, library budgets, consortial participation, and marketplace realities. Additionally, the increased availability of e-books and their acquisitions models have created opportunities for research that compares the efficiency and effectiveness of e-book purchasing models and draws on existing and evolving evaluative models to establish benchmarks for measuring success.
