Preservation Briefs provide in-depth information about various aspects of historic preservation. Many provide guidance on the appropriate treatment of traditional building materials such as slate roofing, plaster, and masonry. Others address architectural features including storefronts and porches, or focus on the reuse of specific building types such as historic gas stations and barns. Additionally, this publication series covers broader themes such as how to understand architectural character and making historic buildings accessible.

Preservation Tech Notes provide practical information on traditional practices and innovative techniques for successfully maintaining and preserving cultural resources.

The preservation of Cultural Landscapes presents unique issues and challenges. These historic resources range in scale from small formal gardens to large tracts of land. And they include all types of resources from natural features with significance for Indian tribes to roadside features of the early automobile era.
