Special Collections is Carnegie Mellon University’s repository for rare books, manuscripts, and early scientific instruments and calculating machines. Housed in the Fine & Rare Book Rooms (Hunt Library, 4th floor) and the Posner Center, Special Collections originated with the 1964 donation of Rachel McMasters Miller Hunt’s non-botanical books and has grown through the addition of important gifts, including the bequest of Charles J. Rosenbloom, the deposit of the Posner Memorial Collection, and the gift of the Traub-McCorduck collection in 2018.

Areas of collections strength include the history of science, cryptology, and computing; early Shakespeare editions (including the Rosenbloom First Folio); the history of the book; and graphic arts and fine printing.

Special Collections is open to the CMU community and to the public. Curator of Special Collections, Sam Lemley, administers access, interpretation, acquisitions, and research. Contact Special Collections to schedule a research appointment or class visit.

What We Collect

CMU Special Collections acquires books, manuscripts, and artifacts that document the history of science and technology; mechanical, symbolic, and digital computing; cryptology; book history and design; and early English literature. Our collection development strategy is keyed to these collecting priorities and themes, but we consider gifts in other fields on a case-by-case basis.

Temporary Policy for Research & Instruction in Special Collections (Academic Year 2021/2022)
The Special Collections reading room (Hunt Library, 4th floor) is undergoing renovations and remains closed to researchers and class visits. In some cases, alternative arrangements can be made. Please email Sam Lemley to plan a visit for research or instruction. Additionally, in keeping with the University’s current COVID-19 protocols and the Libraries’ COVID-19 protocols we are limiting the number of researchers in Special Collections to allow for safe distancing. Priority will be given to current CMU faculty, staff, and students. Requests from non-affiliates will be reviewed on a case-by-case basis. If you are not a CMU affiliate, please contact Sam Lemley at least two weeks in advance of your intended visit.
