Published by The New York Times in 1971, The Pentagon Papers riveted an already deeply divided nation with startling and disturbing revelations about the United States' involvement in Vietnam. The Washington Post called them "the most significant leaks of classified material in American history" and they remain relevant today as a reminder of the importance of a free press. Indeed, they are a focal point of The Post, a new film by Steven Spielberg about that era. With a new foreword by James L. Greenfield, this edition of the Pulitzer Prize winning series is sure to provoke discussion about government deception and the public's right to know, and shed some light on issues in the past and present so that we can better understand and improve the future.
