Duke University's Rare Book, Manuscript, and Special Collections Library (RBMSCL) contains a significant number of unique items of interest to students and scholars of Slavic and East European Studies, most of which can be easily located in the Duke online library catalog.  Simply conduct an Advanced Search and limit the location to "Special Collections."  Scholars interested in Duke's special collections can also conduct a keyword search in the online Guide to the Cataloged Collections of the William R. Perkins Library, Duke University, which contains information on 5991 archival collections acquired up to 1980 by the Manuscript Department of the William R. Perkins Library (as the RBMSCL used to be known before the Manuscript Department's merger with the Rare Book Room).  For archival collections acquired after 1980, consult the online Finding Aids, which currently describe another 775 archival collections and counting.  In addition to these search engines, you may also wish to consult both RBMSCL's library catalog and picture files, analog versions of which are available for browsing in the RBMSCL's reading room on the first floor of Perkins Library.
