About the Archives
The County Records Management and Archives Program maintains archival records for use by county agencies and public researchers.
Archival records are records that have been identified for permanent retention on agency records retention schedules, records that are included in the Multnomah County Historical Records Inventory, or records that were created in 1920 or earlier.
We are committed to making the archives widely accessible and will work to make your research as straight-forward as possible.

All visitors must follow current facility use and research rules and health and safety guidelines for entering county buildings.
