Among the world-class resources at this circulation library are the research collections, which include the Jerome Robbins Dance Division; Music Division; Rodgers and Hammerstein Archives of Recorded Sound; Billy Rose Theatre Division; and Theatre on Film and Tape Archive. Anyone may access these collections on a library visit.

The Jerome Robbins Dance Division is part museum, part film production center, and part consulting service to the professional dance community.

While the Music Division contains many scores and manuscripts from centuries past, its curatorial mandate is an activist one, placing major emphasis on capturing the creative output of contemporary composers.

The Rodgers and Hammerstein Archives of Recorded Sound is a vital research facility for performers, musicians, scholars, critics and the recording industry. The collection also develops technology that allows for the transfer of sound from obsolete to accessible formats.

The Billy Rose Theatre Division encompasses dramatic performance in all its diversity and is an indispensable resource for artists, writers, researchers, scholars, students and the general public.

Since 1970, the Theatre on Film and Tape Archive (TOFT) has been engaged in a unique documentation effort, recording Broadway, Off-Broadway, and regional theater productions, and dialogues between notable theater personalities.
