The International Schenker Symposium, a conference dedicated to furthering the study of the system of music theory developed by Heinrich Schenker, was held at the Mannes School of Music septennially from 1985 to 2013. The collection contains papers presented and administrative files primarily from the first symposium in 1985, and the fourth symposium in 2006. Audio recordings of portions of the 2006 symposium are also included.

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.
