Snowden is set to tell his story

Metropolitan Books will publish the NSA leaker’s memoir, ‘Permanent Record.’

NEW YORK — Edward Snowden, a former National Security Agency contractor whose leaks of classified documents transformed the debate about government surveillance, is ready to tell his story.

Metropolitan Books, an imprint of Macmillan Publishers, announced Thursday that Snowden’s “Permanent Record” will be released Sept. 17 in more than 20 countries.

According to Metropolitan, Snowden will describe his role in the accumulation of metadata and the “crisis of conscience” that led him to steal a trove of files in 2013 and share them with reporters. Metropolitan spokeswoman Pat Eisemann declined to offer additional details.

Snowden noted in a tweet Thursday that the book would be released on Constitution Day. Snowden, who faces U.S. charges that could land him in prison, is currently living in exile in Moscow, and promotion elsewhere will likely be restricted to interviews done remotely.

He has been widely condemned by intelligence officials, who allege Snowden has caused lasting damage to national security, and defended by civil libertarians and other privacy advocates who praise Snowden for revealing the extent of information the government was gathering.

Notable revelations included a massive program collecting metadata on millions of domestic phone calls.

“Edward Snowden decided at the age of 29 to give up his entire future for the good of his country,” John Sargent, CEO of Macmillan, said in a statement. “He displayed enormous courage in doing so, and like him or not, his is an incredible American story. There is no doubt that the world is a better and more private place for his actions. Macmillan is enormously proud to publish ‘Permanent Record.’ ”

Financial details were not disclosed for a book that was itself a covert project, quietly acquired a year ago by Macmillan and identified under code names in internal documents. Snowden’s primary contact with the publisher was his principal legal adviser, Ben Wizner, director of the American Civil Liberties Union’s Speech, Privacy, and Technology Project.
