The History of Science Collections of the University of Oklahoma Libraries was established in 1949 with an initial gift from OU alumnus Everette Lee DeGolyer. Current holdings of nearly 100,000 volumes, representing every field and subject area of science, technology and medicine, include complete sets of first editions of major scientists such as Copernicus, Galileo, Newton and Darwin. Volumes range chronologically from Hrabanus Maurus, Opus de universo (1467), to current publications in the history of science.
