Mary E. Miller and Suzanne M. Ward write: “Academic librarians have long grappled with issues of collection size, quality versus quantity, and maintaining a core collection. In previous eras, libraries provided access to content by acquiring and owning print copies of titles to allow immediate access to users. This strategy is no longer sustainable. But more importantly, it no longer serves the best interests of most academic library users. The realities of space and resource availability and the demand for new services are forcing even the largest and best-funded academic libraries to acknowledge that they cannot, in fact, keep everything.”
