Hardly a week passes without some high-profile court case that features intellectual property at its center. But how did the belief that one could own an idea come about? And how did that belief change the way humankind lives and works?

William Rosen, author of Justinian's Flea, seeks to answer these questions and more with The Most Powerful Idea in the World. A lively and passionate study of the engineering and scientific breakthroughs that led to the steam engine, this book argues that the very notion of intellectual property drove not only the invention of the steam engine but also the entire Industrial Revolution: history’s first sustained era of economic improvement. To do so, Rosen conjures up an eccentric cast of characters, including the legal philosophers who enabled most the inventive society in millennia, and the scientists and inventors—Thomas Newcomen, Robert Boyle, and James Watt—who helped to create and perfect the steam engine over the centuries. With wit and wide-ranging curiosity, Rosen explores the power of creativity, capital, and collaboration in the brilliant engineering of the steam engine and how this power source, which fueled factories, ships, and railroads, changed human history.   

Deeply informative and never dull, Rosen's account of one of the most important inventions made by humans is a rollicking ride through history, with careful scholarship and fast-paced prose in equal measure.

Out of the tradition of those long-gone days of great, heaving steam locomotives and endless rail lines comes this remarkable selection of vintage cards, a treasure trove selected from John Vander Maas' consummate collection at the University of Iowa Libraries.

This lavish volume is the first general book-length work devoted to the once-ubiquitous railroad picture postcard. It comprises an introductory essay and an album of cards. The former fully examines the nature of the postcard craze, which reached its zenith about 1910, and discusses why images of American railroads played such an important part in the card phenomenon. The album divides an engaging assortment of more than 150 representative views into five sections: “Trains and Rolling Stock,” “Depots and Railway Structures,” “The Railroad Corridor,” “People and Railroads,” and “The Lighter Side of Railroading.”

Railroad historians, train enthusiasts, postcard collectors, and all other readers will find much to interest them in this selection of images. Not only are the cards themselves visually striking, but they convey a sense of how important railroads once were to the nation's citizenry. The sight of steaming locomotives and the hustle and bustle associated with “train time” caused hearts to quicken. These feelings made views of railroad scenes popular with buyers of postcards and now with latter-day railroad fans and card collectors.

Historians of midwestern railroading during the early part of the twentieth century have generally focused on the production of railroad company histories while ignoring the regional view. Fortunately for railway historians and buffs, coincidentally with the zenith of the Railway Age, the national fad for producing and mailing postcards was at its height. Millions of cards, including "real-photo" images, were produced between 1905 and 1915. Roger Grant has selected more than a hundred representative picture postcards to visualize the principal themes and characteristics that gave this dynamic industry its distinctive regional features.

By the turn of the century, the railroad map of the Midwest was unequaled. Anyone who examined it carefully sensed that this was the vital center of America's massive network of steel rails. Depots erected in the western prairie environment were spartan, with only minor decoration, but those in the Midwest usually mirrored more ornate New England styles. These features are often reflected in the images in this heavily illustrated book, which depicts the spare but strong pioneering spirit of the enterprise.

For nearly seventy years, John J. Young Jr. photographed railroads. With unparalleled scope and span, he documented the impact and beauty of railways in American life from 1936 to 2004.

As a child during the Great Depression, J. J. Young Jr. began to photograph railroads in Wheeling, West Virginia. This book collects over one hundred fifty of those images—some unpublished until now—documenting the railroads of Wheeling and the surrounding area from the 1930s until the 1960s.

The photographs within this book highlight the major railroads of Wheeling: the Baltimore & Ohio, the Pennsylvania, the Wheeling & Lake Erie, the Pittsburgh & West Virginia, the New York Central, and the industrial and interurban rail lines that crisscrossed the region. These images capture the routine activities of trains that carried passengers and freight to and from the city and its industries, as well as more unusual traffic, such as a circus-advertising car, the General Motors Train of Tomorrow, and the 1947 American Freedom Train.
