PREFACE

The National Register of Historic Places is the official Federal list of districts, sites, buildings, structures, and objects significant in American history, architecture, archeology, engineering, and culture. National Register properties have significance in the prehistory or history of their community, State, or the nation. The National Register is maintained by the National Park Service on behalf of the Secretary of the Interior.

National Register Bulletins provide guidance on how to identify, evaluate, document, and register significant properties. This bulletin is designed to help preparers properly select, define, and document boundaries for National Register listings and determinations of eligibility. It includes basic guidelines for selecting boundaries to assist the preparer in completing the National Register Registration Form. Examples of a variety of property types are presented. These examples illustrate several ways to address boundary issues. This bulletin was prepared by Donna J. Seifert, archeologist, under a cooperative agreement between the National Conference of State Historic Preservation Officers and the National Park Service.
