An unfortunate accident (a fractured left hip) occurred as the last pages of this book were being written. The event placed an extra burden on my family and friends, causing me to call on them for even more help than usual. And they all came through, in some cases meeting my almost impossible requests. My wife, Barbara, in addition to serving as chief practical nurse on twenty-four hour, seven days a week duty, proofread and improved the text. My son David assisted me in countless ways. William Bryson was always available to solve problems for a computer illiterate. Bob Tarleton provided invaluable bibliographic help and source material. Bill and Harriet Scott were always ready to look into their unequaled library of Soviet reference materials to answer questions and furnish citations. David Murphy was vigilant for pertinent information uncovered in the course of his own research.
