The book includes six chapters that cover Virginia history from initial settlement through the 20th century plus one that deals with the important role of underwater archaeology. Written by prominent archaeologists with research experience in their respective topic areas, the chapters consider important issues of Virginia history and consider how the discipline of historic archaeology has addressed them and needs to address them . Changes in research strategy over time are discussed , and recommendations are made concerning the need to recognize the diverse and often differing roles and impacts that characterized the different regions of Virginia over the course of its historic past. Significant issues in Virginia history needing greater study are identified.

By the start of the 20th century, the U.S. Navy had developed a fledgling salvage capability. Today, under the aegis of the Supervisor of Salvage, the Navy routinely handles assignments around the world, guarding U.S. naval and maritime interests and responding to requests for assistance from our allies. Mud, Muscle, and Miracles takes its reader on a journey through the evolution of salvage--from the construction of a cofferdam to reveal battleship Maineat the bottom of Havana harbor in 1911 to the use of side-scan sonar and remotely operated vehicles to recover aircraft debris and complete vessels from the depths. The story is one of masterful seamanship, incomparable engineering, and absolute ingenuity and courage. It is also the history of one of our nation's longest-lasting public-private partnerships--that of the commercial salvage industry and the U.S. Navy. The second edition updates U.S. Navy salvage history through the beginning of the 21st century and chronicles 18 additional, precedent-setting marine salvage and deep-ocean recovery operations.

Before Palm Pilots and iPods, PCs and laptops, the term "computer" referred to the people who did scientific calculations by hand. These workers were neither calculating geniuses nor idiot savants but knowledgeable people who, in other circumstances, might have become scientists in their own right. When Computers Were Human represents the first in-depth account of this little-known, 200-year epoch in the history of science and technology. Beginning with the story of his own grandmother, who was trained as a human computer, David Alan Grier provides a poignant introduction to the wider world of women and men who did the hard computational labor of science. His grandmother's casual remark, "I wish I'd used my calculus," hinted at a career deferred and an education forgotten, a secret life unappreciated; like many highly educated women of her generation, she studied to become a human computer because nothing else would offer her a place in the scientific world. The book begins with the return of Halley's comet in 1758 and the effort of three French astronomers to compute its orbit. It ends four cycles later, with a UNIVAC electronic computer projecting the 1986 orbit. In between, Grier tells us about the surveyors of the French Revolution, describes the calculating machines of Charles Babbage, and guides the reader through the Great Depression to marvel at the giant computing room of the Works Progress Administration. When Computers Were Human is the sad but lyrical story of workers who gladly did the hard labor of research calculation in the hope that they might be part of the scientific community. In the end, they were rewarded by a new electronic machine that took the place and the name of those who were, once, the computers.

This volume initiates a new series of books on maritime or underwater archaeology, and as the editor of the series I welcome its appearance with great excitement. It is appropriate that the first book of the series is a collection of articles intended for gradu ate or undergraduate courses in underwater archaeology, since the growth in academic opportunities for students is an important sign of the vitality of this subdiscipline. The layman will enjoy the book as well. Academic and public interest in shipwrecks and other submerged archaeological sites is indicated by a number of factors. Every year there are 80 to 90 research papers presented at the Society for Historical Archaeology's Conference on Historical and Underwater Archaeology, and the Proceedings are published. Public interest is shown by extensive press coverage of shipwreck investigations. One of the most important advances in recent years has been the passage of the Abandoned Shipwreck Act of 1987, for the first time providing national-level law con cerning underwater archeological sites. The legislation has withstood a number of legal challenges by commercial treasure salvors, a very hopeful sign for the long-term pres ervation of this nonrenewable type of cultural resource. The underwater archaeological discoveries of 1995 were particularly noteworthy. The Texas Historical Commission discovered the Belle, one of La Salle's ships, and the CSS Hunley was found by a joint project of South Carolina and a private nonprofit organization called NUMA.
