Book Description
United States Diplomatic Codes and Ciphers, 1775-1938 is the first basic reference work on American diplomatic cryptography. Weber's research in national and private archives in the Americas and Europe has uncovered more than one hundred codes and ciphers. Beginning with the American Revolution, these secret systems masked confidential diplomatic correspondence and reports.During the period between 1775 and 1938, both codes and ciphers were employed. Ciphers were frequently used for American diplomatic and military correspondence during the American Revolution. At that time, a system was popular among American statesmen whereby a common book, such as a specific dictionary,was used by two correspondents who encoded each word in a message with three numbers. In this system, the first number indicated the page of the book, the second the line in the book, and the third the position of the plain text word on that line counting from the left. Codes provided the most common secret language basis for the entire nineteenth century.Ralph Weber describes in eight chapters the development of American cryptographic practice. The codes and ciphers published in the text and appendix will enable historians and others to read secret State Department dispatches before 1876, and explain code designs after that year.

Book Description
When the United States declared war on Germany in April 1917, it was woefully unprepared to wage a modern war. Whereas their European counterparts already had three years of experience in using code and cipher systems in the war, American cryptologists had to help in the building of a military intelligence unit from scratch. This book relates the personal experiences of one such character, providing a uniquely American perspective on the Great War. It is a story of spies, coded letters, plots to blow up ships and munitions plants, secret inks, arms smuggling, treason, and desperate battlefield messages. Yet it all begins with a college English professor and Chaucer scholar named John Mathews Manly. In 1927, John Manly wrote a series of articles on his service in the Code and Cipher Section (MI-8) of the U.S. Army’s Military Intelligence Division (MID) during World War I. Published here for the first time, enhanced with references and annotations for additional context, these articles form the basis of an exciting exploration of American military intelligence and counter-espionage in 1917-1918. Illustrating the thoughts of prisoners of war, draftees, German spies, and ordinary Americans with secrets to hide, the messages deciphered by Manly provide a fascinating insight into the state of mind of a nation at war.

Book Description
During the 1920s Herbert O. Yardley was chief of the first peacetime cryptanalytic organization in the United States, the ancestor of today's National Security Agency. Funded by the U.S. Army and the Department of State and working out of New York, his small and highly secret unit succeeded in breaking the diplomatic codes of several nations, including Japan. The decrypts played a critical role in U.S. diplomacy. Despite its extraordinary successes, the Black Chamber, as it came to known, was disbanded in 1929. President Hoover's new Secretary of State Henry L. Stimson refused to continue its funding with the now-famous comment, "Gentlemen do not read other people's mail." In 1931 a disappointed Yardley caused a sensation when he published this book and revealed to the world exactly what his agency had done with the secret and illegal cooperation of nearly the entire American cable industry. These revelations and Yardley's right to publish them set into motion a conflict that continues to this day: the right to freedom of expression versus national security. In addition to offering an exposé on post-World War I cryptology, the book is filled with exciting stories and personalities.

Book Description
This supplement to The Papers of Henry Clay contains documents discovered too late to be included in the proper chronological sequence in earlier volumes. Spanning the years from 1793 to 1852, the items shed important light on Clay's early years in Kentucky, his legal career, and his work for the Bank of the United States. Material dealing with the "Corrupt Bargain" charge is particularly rich, and many of the letters that appear in this volume fill gaps in exchanges already published. Clay's correspondence with Benjamin Watkins Lee of Virginia and Mary Bayard, wife of Delaware senator Richard Henry Bayard, is especially interesting. An essay on Clay portraits by Clifford Amyx, professor emeritus of art at the University of Kentucky, provides a detailed discussion of the paintings, statues, busts, engravings, and daguerreotypes that featured Clay as the subject. Appended to the essay is a calendar listing each major work, the artist, date of completion, and present location. A comprehensive bibliography of works cited in the entire series will benefit researchers seeking information in addition to that provided in the annotations. This supplement is an essential addition to the earlier volumes in the series.
