The University of Delaware Press (UDP) is a publishing house and a department of the University of Delaware in the United States, whose main campus is at Newark, Delaware, where the University Press is also based.Established in the early 1970s, the UDP published few books until 1975, when it joined the Associated University Presses (AUP) consortium. This allowed the UDP to choose works to publish under its imprint and control, while the AUP takes charge of production and distribution. When Associated University Presses ceased operating in 2010, a new distribution agreement was struck with Rowman & Littlefield.
