NATO Archives Public Disclosure Programme: Processes and Access (nato.int)

• Systematic declassification occurs annually for records over 30 years old.
• Ad-hoc requests allow targeted declassification, e.g., for US FRUS series.
• Online access to 105,000 documents via NATO Archives Online.

"The NATO Archives has declassified over 554,000 documents through its Public Disclosure Programme. Documents older than 30 years are systematically reviewed annually, with member states having a silence period for approval. Ad-hoc requests from researchers and journalists are also processed. Access is available via the Reading Room in Brussels and an online portal with over 105,000 freely downloadable PDFs. The archive officially opened in 1999."
