With holdings of nearly three-quarters of a million items, the Sibley Music Library is recognized as one of the world’s preeminent research libraries devoted to all aspects of the study of music. Materials are assigned either to the circulating collections or to the Ruth T. Watanabe Special Collections, which includes rare books, archival collections, the Eastman School of Music Archives, and the Eastman Audio Archive.
The circulating collections include scores, books, journals, microforms, and audio and visual recordings. Some of these formats, such as current periodicals, recordings, and microforms, circulate for use primarily within the Library. Scores and books are loaned for use; the precise loan periods are specified under “Circulation Policies.”
