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

Board meeting minutes, letters, and photographs of Half Hollow Hills Library.
A collection of photographic postcards depicting the rural town of Sardinia, New York in the early 20th century.
Photographs, slides, postcards, books, magazines and other miscellany documenting the history of Massapequa.
This collection highlights images and documents reflecting the College's move from its downtown Troy location to a permanent multi-building campus on the outskirts of the city to meet the demands of a growing student body and faculty, the need for varied instructional resources, and  continued growth as an established institution of higher education.
This collection reflects the diversity of the student body  as well as the broadening scope of the curriculum as the Institute responded to the wants and needs of employers and students in the region.
