Division of Rare & Manuscript Collections
Housed on the lowest level of Kroch Library, the Division of Rare and Manuscript Collections is open for research Monday-Friday and some Saturdays during the semester. 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 on at the collection (rather than at the item) level. Notable collections are described here. Many of Cornell's 19th-century periodicals must be examined in the rare reading room.
