Like the Washington Post's coverage of Watergate, this book is the result of a collaborative effort with our colleagues executives, editors, reporters, librarians, telephone operators, news aides. Since June 17 1972, we have had their assistance, support and advice. Some persons stand out. Our particular gratitude to Katharine Graham, Benjamin C. Bradlee, Howard Simons, Harry M. Rosenfeld, Barry Sussman and etc. This book would not have been possible without the work of Robert Fink, who assisted us in the research, lent us his ideas and gently offered us his criticism.
