The Washington County Law Library was established by order of the Washington County Court on July 3, 1926. It is supported by Oregon legislative appropriation and operated by Washington County in consultation with the Circuit Court Presiding Judge and Washington County Bar Association. The Washington County Board of Commissioners issued a proclamation recognizing the Law Library's 90th anniversary in 2016. This slide show (PDF) illuminates some of our history over those 90 years.

Our mission is to provide research training and legal reference assistance, access to a variety of general and specialized legal information resources and tools, and a comfortable, welcoming, and usable space for everyone engaged with the justice system, including litigants and those facing legal issues, attorneys, court staff, the judiciary, and other governmental organizations.
