The articles published are based on more than 700 classified files on past and present detainees at the Guantánamo Bay prison, including the government's assessment of the dangers the individuals represent. The files are from February 2002 to January 2009, and some of the information may have been superseded by later, still undisclosed assessments made by the Obama administration or by more highly classified documents.
The Guantánamo files were part of a huge trove of secret documents leaked last year to the anti-secrecy organisation WikiLeaks. They were made available to The New York Times by another source on the condition of anonymity. National Public Radio and the British newspaper The Guardian are also producing reports based on the documents.
The files include allegations that cannot be independently verified and have in many cases been contested by detainees or their lawyers. As with earlier documents from this cache the battlefield logs from Afghanistan and Iraq and the secret State Department cables The Times has redacted or withheld information that would put lives at risk, including the identities of some informants. An exception was made for certain high-profile inmates who have already been publicly identified as sources of information.
The Times has prepared an extensive digital repository of information about the Guantánamo detainees, compiled from a variety of public sources and now supplemented by these secret files. It can be found at nytimes.com/guantanamo-files. — © New York Times News Service
