Over the concluding decades of the twentieth century, the historic preservation community increasingly turned its attention to modern buildings, including bungalows from the 1930s, gas stations and diners from the 1940s, and office buildings and architectural homes from the 1950s. Conservation efforts, however, were often hampered by a lack of technical information about the products used in these structures, and to fill this gap Twentieth-Century Building Materials was developed by the U.S. Department of the Interior’s National Park Service and first published in 1995. Now, this invaluable guide is being reissued—with a new preface by the book’s original editor. With more than 250 illustrations, including a full-color photographic essay, the volume remains an indispensable reference on the history and conservation of modern building materials. Thirty-seven essays written by leading experts offer insights into the history, manufacturing processes, and uses of a wide range of materials, including glass block, aluminum, plywood, linoleum, and gypsum board. Readers will also learn about how these materials perform over time and discover valuable conservation and repair techniques. Bibliographies and sources for further research complete the volume. The book is intended for a wide range of conservation professionals including architects, engineers, conservators, and material scientists engaged in the conservation of modern buildings, as well as scholars in related disciplines.

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.

Two men played a crucial role in the creation and early history of the National Park Service: Stephen T. Mather, a public relations genius of sweeping vision, and Horace M. Albright, an able lawyer and administrator who helped transform that vision into reality. In Creating the National Park Service, Albright and his daughter, Marian Albright Schenck, reveal the previously untold story of the critical "missing years" in the history of the service. During this period, 1917 and 1918, Mather's problems with manic depression were kept hidden from public view, and Albright, his able and devoted assistant, served as acting director and assumed Mather's responsibilities. Albright played a decisive part in the passage of the National Park Service Organic Act of 1916; the formulation of principles and policies for management of the parks; the defense of the parks against exploitation by ranchers, lumber companies, and mining interests during World War I; and other issues crucial to the future of the fledgling park system. This authoritative behind-the-scenes history sheds light on the early days of the most popular of all federal agencies while painting a vivid picture of American life in the early twentieth century.

Explores the story of Federal contributions to dam planning, design, and construction.

Hold High the Torch, the first of a series of regimental and squadron histories by the Historical Branch, G-3 Division, Headquarters U.S. Marine Corps, is designed primarily to acquaint the members of the 4th Marines, past and present, with the history of their regiment. In addition, it is hoped this volume will enlarge public understanding of the Marine Corps’ worth both in limited war and as a force in readiness. During most of its existence the 4th Marines was not engaged in active military operations, but service of the regiment in China, the Dominican Republic, and off the west coast of Mexico, was typical of the Marine Corps’ support of national policy. In many of its combat operations, the 4th Marines was only one element of a much larger force. In other instances, as in the Dominican Republic and China, the regiment was a subordinate unit in situations which were essentially political and diplomatic. Only so much of these higher echelon activities as are essential to an understanding of the 4th Marines story have been told. This is a regimental history and the focus is therefore on the 4th Marines.
