The County Records Management 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.

The archival records maintained by the County Records Management Program have varying degrees of arrangement and description. The inventories and descriptive aids listed below are not exhaustive - there are many archival records not included. Please contact the County Records Management Program for additional reference information, or refer to our Locating Records section of this web site for answers to common reference and referral questions.

The descriptive aids listed below fall into the following categories:

  • Administrative/Biographical Histories: These are a basic history of the organization or individual covered by the particular archival group of records, or "accession".
  • Descriptive Aids: These provide a detailed description of a particular archival accession, including its scope and content, arrangement, a description of various record series within the accession, folder listings, and other pertinent information.
  • Other Resources: Information about resources available elsewhere that are pertinent to the record collection.
  • Folder Listings: Listings of folder headings developed from box inventories. In general, these will be listings that are longer in length than can be easily included in a descriptive aid, or represent rough initial inventories of collections which have not undergone complete archival appraisal, description, and processing.

The county archives is available for research by appointment only. It is open from 8 a.m. until 4 p.m., Monday through Thursday, except on official county holidays. To make an appointment, please contact program staff listed below. We are committed to making the archives widely accessible and will work to make your research as straight-forward as possible.
