"Investigating Iwo encourages us to explore the connection between American visual culture and World War II, particularly how the image inspired Marines, servicemembers, and civilians to carry on with the war and to remember those who made the ultimate sacrifice to ensure victory over the Axis Powers. Chapters shed light on the processes through which history becomes memory and gains meaning over time. The contributors ask only that we be willing to take a closer look, to remain open to new perspectives that can deepen our understanding of familiar topics related to the flag raising, including Rosenthal's famous picture, that continue to mean so much to us today"--

The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

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.

For 100 years, the Congressional Research Service (CRS) has been charged with providing nonpartisan and authoritative research and analysis to inform the legislative debate in Congress. This has involved a wide range of services, such as written reports on issues and the legislative process, consultations with Members and their staff, seminars on policy and procedural matters, and congressional testimony. The Government and Finance Division at CRS took a step back from its intensive day-to-day service to Congress to analyze important trends in the evolution of the institution-its organization and policymaking process-over the last many decades. Changes in the political landscape, technology, and representational norms have required Congress to evolve as the Nation's most democratic national institution of governance. The essays in this print demonstrate that Congress has been a flexible institution that has changed markedly in recent years in response to the social and political environment.
