The History of Science Collections are a part of the University Libraries system and serve students, faculty, and scholars in the history of science. Holdings range chronologically from Hrabanus Maurus' Opus de universo (the Collections' oldest book, printed before 20 July 1467) to current publications in the history of science. They represent an excellent cross-section for the history of printing and publishing. The purposes of the History of Science Collections are to identify, collect, and preserve the published record of the history of science, and also to provide access for research and teaching.
