Research Our Records

Online Public Access

Search the online catalog and other National Archives resources at once for information about our records.

Thank you for trying the Online Public Access (OPA) system. OPA is our prototype portal for searching multiple National Archives electronic resources at once.

Please note that the data in OPA has not been updated since September 2011. We are currently working on making more data searchable through OPA. You may want to check the Archival Research Catalog (ARC) for information until the OPA system has been updated.

We encourage you to explore OPA as we continue to make enhancements to the system.

We would like to hear your comments about Online Public Access. Contact us at and let us know.
