Information "Secrecy" Oversight Office
The restoration of classified status to more than 55,000 previously declassified pages began in 1999, when the Central Intelligence Agency and five other agencies objected to what they saw as a hasty release of sensitive information after a 1995 declassification order signed by President Bill Clinton. It accelerated after the Bush administration took office and especially after the 2001 terrorist attacks, according to archives records.
..."It doesn't make sense to create a category of documents that are classified but that everyone already has," said Meredith Fuchs, general counsel of the National Security Archive, a research group at George Washington University. "These documents were on open shelves for years."
..."I think this is a travesty," said Dr. Anna K. Nelson, a foreign policy historian at American University, who said she believed that some reclassified material was in her files. "I think the public is being deprived of what history is really about: facts."
