Field Trips

A field trip to the Gilder Lehrman Institute of American History gives students the unique opportunity to learn history from real documents, up close with no display cases! This exciting experience creates tangible links to the past as students connect with original materials.


Materials from the Gilder Lehrman Collection are exhibited at the New-York Historical Society and at other prominent institutions around the country. Please visit our Museum Exhibitions page for more details.

Remote Access for University and Research Libraries

A comprehensive research database of the Collection with images is available by subscription through Adam Matthew: Primary Sources for Teaching and Research.

Klingenstein Library, Tuesday–Friday, 10 a.m.–4:45 p.m.
