Housed on the lowest level of Kroch Library, the Division of Rare and Manuscript Collections is open for research Monday-Friday, 10:30am-4:30pm, and on some Saturday afternoons. Please consult their web site for specific hours. This is Cornell's largest collection of archival and rare book materials. While books are listed in the library catalog, archival collections are described at the collection (rather than at the item) level, and many have further details on collection contents and arrangement listed on finding guides. Notable collections are described here.
Researchers must register to use the Rare collections. To register: Fill out this online form, then bring a photo ID to the RMC Reference Desk when you come in to do your research.
Archival material cannot typically be checked out or interlibrary loaned, and usually not photocopied or scanned (except by a staff member, and for a fee). However, many archival institutions will allow you to take photos of pages.
