# Celebrating 90 Years of the Historic American Buildings Survey

The Historic American Buildings Survey (HABS, est. 1933) is the nation's first federal preservation program to document America's architectural heritage. This effort, later joined by the Historic American Engineering Record (HAER, est. 1969) and the Historic American Landscapes Survey (HALS, est. 2000), is administered through the National Park Service. The series in combination have recorded America's built environment in multiformat surveys comprising drawings, photographs and written histories for more than 44,000 historic structures and sites dating from Pre-Columbian times to the 21st century. Catherine Lavoie, chief of the Historic American Buildings Survey in the Heritage Documentation Programs office of the National Park Service, discusses the vital role played by Library of Congress curator Leicester B. Holland and the well-loved collection that makes it accessible to all.
