The New School Archives staff created the Mannes College of Music administrative records collection by integrating several collections documenting the Mannes College of Music (now, Mannes School of Music). The collection includes correspondence, event flyers, photographs, legal records, meeting minutes, illustrations, administrative records and reports.

This collection contains documentation of The New School Archives, established in 2012, and its predecessor, the Kellen Design Archives (also known as the Anna-Maria and Stephen Kellen Archives Center). Wendy Scheir became director of the Archives in 2008, taking over from Xenophon T. Barber. The records cover both directorships and relate to Archives exhibitions, publicity, collecting, preservation, strategic planning, and grant applications. Also included are photographs of the Archives space and staff.

This collection consists of archived websites published by The New School and members of the university community from 2016 to 2022. The archived websites include university events, exhibits, student and faculty websites, publications, and departmental websites.

This collection consists of administrative records produced by Parsons School of Design administrative offices, including Admissions; the Board of Governors; Career Services; Human Resources; Student Services; and the Development Office, including Alumni Relations and External Partnerships. The contents primarily comprise printed promotional materials, directories and lists, with a small amount of photographs and email correspondence.
