Greenacre Reference Library


The Greenacre Reference Library, MAS’ research library, is devoted to the complex ecology of New York City and beyond: urban culture and the environment, natural and built.

This collection, established in 1978—books, newspaper clippings, files, pamphlets, magazines, letters, and testimony culled from the journalistic record—is an invaluable resource to anyone interested in researching the development and future of our city.  The number of clippings files alone, both paper and digitized, exceeds 5,000 and covers architecture and art, parks, open and public spaces, the waterfront, transportation and other infrastructure, urban planning, historic preservation, and New York City’s history and its diversity of culture and neighborhoods.

Scholars, students and educators, journalists, preservationists, and livable city and environmental advocates will find a rich source of information in a supportive setting.

The library is located within the MAS’ offices on the 16th floor at 111 West 57th Street, New York, NY.  A library manager and volunteers are available to assist library users with their research.  Materials can be photocopied or scanned and emailed at a charge of $.25 a page.  Internet service is also available at the library.  An appointment is always required.  To schedule a visit during office hours Monday through Friday, or to make an inquiry, please contact Erin Butler by phone, 212-935-3960 x1274 or email her at ebutler[at] a visit is not possible, questions may be answered by filling out and submitting the form at Ask MAS.
