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 of formerly bound concert programs for the Mannes Chamber Ensemble and the Mannes Orchestra was compiled by former Mannes School of Music orchestra manager Kelly Edwards.

Collection consists of concert programs for Mannes School of Music student and faculty recitals as well as promotional materials for other school performances. Also includes press releases and event calendars. Mannes was established in 1916 by David and Clara Mannes and became a division of The New School in 1989. As of 2018, Mannes is part of The New School's College of Performing Arts.

Collection consists of Mannes College The New School for Music (now, Mannes School of Music) concert program text covering four consecutive academic years.

The New School began inputting course information into the database, Banner [banner.newschool.edu] around 2007. As of 2021, all New School course data is input into Banner through an interface called Tableau. This collection contains course data that has either been downloaded from Banner or from other New School websites. All divisions and undergraduate schools are represented, but courses for each college are not comprehensive.

Included in this record group are publications issued on a regular basis by The New School, and schools, divisions and offices of the university, including publications of Parsons School of Design and Mannes School of Music dating prior to their affiliation with The New School.
