DOWNLOAD EBOOK“Anyone who is interested in Civil War logistics, wartime railroads, and the Cumberland Valley of Pennsylvania needs to read this study.” —Eric J. Wittenberg, award-winning historian and author The Civil War was the first conflict in which railroads played a major role. Although much has been written about their role in general, little has been written about specific lines. The Cumberland Valley Railroad, for example, played an important strategic role by connecting Hagerstown, Maryland to Harrisburg, Pennsylvania. Its location enhanced its importance during some of the Civil War’s most critical campaigns. Because of its proximity to major cities in the Eastern Theater, the Cumberland Valley Railroad was an enticing target for Confederate leaders and an invaluable resource for the Union Army. In October 1859, abolitionist John Brown used the CVRR in his fateful Harpers Ferry raid. The line was under direct threat by invading Confederates during the Antietam Campaign, and the following summer suffered serious damage during the Gettysburg Campaign. In 1864, Rebel raiders burned much of its headquarters town, Chambersburg, including the homes of many CVRR employees. The railroad was as vital to residents of the bustling and fertile Cumberland Valley as it was to the Union war effort. Targeted Tracks is grounded on the railway’s voluminous reports, the letters and diaries of local residents and Union and Confederate soldiers, official reports, and newspaper accounts. The primary sources, combined with the expertise of the authors, bring this largely untold story to life. “Mingus and Wingert have done a splendid job telling the story of the industrial, economic, social, and military history of the CVRR . . . engaging.” —Ted Alexander, chief historian (ret.), Antietam National Battlefield

DOWNLOAD EBOOKElectric relays pervade the electronics that dominate our world. They exist in many forms, fulfill many roles, and each have their own behavioral nuances and peculiarities. To date, there exists no comprehensive reference surveying the broad spectrum of electric relays, save one-Electric Relays: Principles and Applications. This ambitious work is not only unique in its scope, but also in its practical approach that focuses on the operational and functional aspects rather than on theory and mathematics. Accomplished engineer Dr. Vladimir Gurevich builds the presentation from first principles, unfolding the concepts and constructions via discussion of their historical development from the earliest ideas to modern technologies. He uses a show-not-tell approach that employs nearly 1300 illustrations and reveals valuable insight based on his extensive experience in the field. The book begins with the basic principles of relay construction and the major functional parts, such as contact and magnetic systems. Then, it devotes individual chapters to the various types of relays. The author describes the principles of function and construction for each type as well as features of several relays belonging to a type that operate on different principles. Remarkably thorough and uniquely practical, Electric Relays: Principles and Applications serves as the perfect introduction to the plethora of electric relays and offers a quick-reference guide for the experienced engineer.

DOWNLOAD EBOOKThis landmark scientific reference for scientists, researchers, and students of marine biology tackles the monumental task of taking a complete biodiversity inventory of the Gulf of Mexico with full biotic and biogeographic information. Presenting a comprehensive summary of knowledge of Gulf biota through 2004, the book includes seventy-seven chapters, which list more than fifteen thousand species in thirty-eight phyla or divisions and were written by 138 authors from seventy-one institutions in fourteen countries. This first volume of Gulf of Mexico Origin, Waters, and Biota, a multivolumed set edited by John W. Tunnell Jr., Darryl L. Felder, and Sylvia A. Earle, provides information on each species' habitat, biology, and geographic range, along with full references and a narrative introduction to the group, which opens each chapter.
