This collection consists of concert and recital programs from the Mannes College of Music, and other organizations, compiled by soprano Dorothy Clark Bergquist and bassoonist Peter Bergquist, who graduated with bachelor's degrees from Mannes in 1956 and 1958 respectively, and served as Mannes Extension Division faculty for a period afterward.

This collection consists of transcripts of seventeen interviews with Esther Hoffman Wexler (1918-2014), conducted by her cousin, Lawrence Freund, between 2012 and 2014. Hoffman, a Canadian-born concert pianist and a longtime piano teacher at the Mannes College of Music (which became a division of The New School in 1989), discusses her life experiences and her career as a musician and as a teacher in New York City and Toronto.
