NISO Publishes Recommended Practice on Demand Driven Acquisition of Monographs

The National Information Standards Organization (NISO) announces the publication of a new recommended practice, Demand Driven Acquisition of Monographs (NISO RP-20-2014). Demand driven acquisition (DDA), also referred to as patron-driven acquisition, is a method used by libraries for collection development where monographs are purchased at their point of need when selected by users from a pool of potential titles.
