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.

Friedrich List (1789-1846) was a prophet of social market economy, national economy and the infant-industry theory. In this comprehensive biography the international influence and reception of List’s theories is presented together with his extraordinary vita. List was a notable early advocate of economic integration of the many separate states of 19th century Germany. His basic theory is that of productive resources and the need to protect infant industries until they have matured enough to stand alone. He is recognized as a visionary economist with social responsibility and as an influential railway pioneer. He was a liberal and a democrat who promoted an extended representative democracy, including respect for human rights and civil liberties, to accompany industrial development. His highly influential main work “The National System of Political Economy” has been translated into many languages. Eugen Wendler, the renowned author and List expert, not only builds upon his many years of research, but also discusses several new sources. This richly illustrated book is as informative as it is well written.
