The first Geological Survey record setting forth the history of the boundaries of the United States and the several States and Territories was prepared by Henry Gannett, assisted by Franklin G. Butterfield, and was published as Bulletin 13 of the Geological Survey in 1885. The second edition, revised and enlarged by Henry Gannett, was published as Bulletin 171 in 1900. The third edition, also revised by Gannett, was published as Bulletin 226 in 1904. A revision and enlargement of Bulletin 226, which included additional matter incidentally connected with boundaries, was prepared by Edward M. Douglas and issued in 1923 as Bulletin 689. It was again revised by Douglas in 1930 as Bulletin 817.

The present bulletin, prepared in 1964, is a revision of the 1932 edition of Bulletin 817. The revisions include clarification and modification of descriptions of certain boundaries, some of which are based on court decisions or international agreements; they also include more accurate figures for certain statistical data and numerous minor additions and deletions as appropriate.

Many Government agencies and officials, particularly the following, supplied useful information: Bureau of Land Management, Department of the Interior; Office of Territories, Department of the Interior; Bureau of the Census, Department of Commerce; Coast Guard, Department of the Treasury; Coast and Geodetic Survey, Department of Commerce; Oceanographic Office, Department of the Navy; U.S. Antarctic Programs, Department of Defense; The Geographer, Department of State.

Special acknowledgment should be made to Mr. William H. Richards of the Bureau of Land Management and Messrs. H. S. Lewis, W. E. Baird, and A. T. Munson of the Geological Survey for their substantial contributions that greatly facilitated the preparation of the volume.

To aid in the maintenance of current data for this publication, readers are requested to report any errors or obsolete information that comes to their attention.
