Mission Statement

Our mission is to serve the public and agencies of King County by collecting, preserving, holding in trust, and facilitating access to County records of enduring historical value that document its land, people, culture, and governance. Through our service, we strive to foster appreciation and understanding of King County’s origins and continuing history.

Collections

We are a repository of historical King County government records, which are open to public view. Over three hundred collections comprising over 18,000 cubic feet, some dating back to 1853, serve as a permanent source of information about activities, programs, and decisions of County agencies and elected officials. Our records are in many formats, including paper, photographs, maps, and audio-visual materials.

They include legislative records--County Commissioner's resolutions (1853-1968) and County Council ordinances and motions (1969-1999), a special collection of over 6,000 County documents, pre-charter legislation, administration and policy decisions, early road and bridge establishment and inspection records and records and policies from former County Executives.

Some King County government records are also held by the Puget Sound Regional Branch of the Washington State Archives (external link), which began collecting materials before the establishment of the King County Archives program in 1990.
