"Despite the importance of seacoast fortifications and other coast defense measures in the history of the United States, no general bibliography covering these subjects existed in 1985. I attempted to fill that void with a bibliography of United States coast defenses including specific fortifications that the national government and, in some cases, states and localities actually owned and maintained. Since the publication of that bibliography, interest in coast defense has increased and many important new publications have appeared. This updated and revised bibliography includes these new contributions. The bibliography is divided into eight sections: A. Most Useful Guides, Bibliographies, Glossaries, and Other Reference Works B. Other Guides, Bibliographies, Glossaries, and Reference Works C. Manuals, Treatises, and Other Technical Literature D. General Coast Defense History E. General United States Coast Defense History F. Individuals Involved in United States Coast Defense G. United States Regional and State Coast Defense History H. Specific United States Coast Defense Locality and Fort History"
