Items in New York Heritage are organized into collections, which provide additional context for understanding their significance and meaning.

Photographs taken by Sally Savage, primarily of Nyack and surrounding areas.
This collection contains material on the history and development of Schenectady County Community College.
“Sculptures in the Air” showcases videotapes that document the ASL (American Sign Language) literature movement in Rochester from 1972-2007. The recordings capture performances by Deaf poets such as Robert Panara, Clayton Valli, Debbie Rennie, Peter Cook, Ella Mae Lentz, and others performing and analyzing ASL literature works at national conferences, in the classroom, and on stage. This collection strives to be fully accessible: it is captioned, voiced, transcribed, and/or signed.
Complete issues of South of the Mountains, Rockland County's local history quarterly.
