Transparency: Obama orders creation of National Declassification Center

Among the major changes are the following:

* It establishes a National Declassification Center at the National Archives to enable agency reviewers to perform collaborative declassification in accordance with priorities developed by the Archivist with input from the general public.

* For the first time, it establishes the principle that no records may remain classified indefinitely and provides enforceable deadlines for declassifying information exempted from automatic declassification at 25 years.

* For the first time, it requires agencies to conduct fundamental classification guidance reviews to ensure that classification guides are up-to-date and that they do not require unnecessary classification.

* It eliminates an Intelligence Community veto of certain decisions by the Interagency Security Classification Appeals Panel that was introduced in the Bush order.
