The National Security Bureau says it has completely declassified tens of
thousands of political archives it possessed from the Martial Law period and
transferred them to the National Archives.

The Bureau says it took 16 months to review, digitize, and transfer all the
hard copies and digital files it possessed to the National Archives
Administration.

The declassified archives cover a wide range of subjects.

They include "public security and counterintelligence systems during the
Martial Law period," "records on surveillance and public security work
conducted by intelligence agencies," as well as "activities of overseas
independence groups."

But even though it conducted a thorough review, the agency said it could not
determine whether some of the classified files were lost or destroyed ..

.... as archives from decades ago were compiled into folders and stored by
individual officers in charge and there were no itemized records for each
document within each folder.
