The Binghamton University subject file collection is a reference collection of materials relating to and about academic programs, buildings, events, and organizations affiliated with Binghamton University.

This collection contains the records of the Binghamton University Libraries. The Libraries offer resources to support instruction and research at the University. Since 1950, the Libraries' goal has been to support scholarship, teach information literacy, and help connect the university community to research resources. While the Libraries originally focussed on collecting books and microfilm, over the years the collection has grown to include rare materials, data, and digital resources.

This collection includes correspondence, photographs, business and local history research files, maps and other materials of Josiah T. Newcomb (1911 - 1981), director of the Binghamton University Library from 1953 to 1971 and Broome County Historian.
