The guide presents an overview of the textual and microfilmed records located at the Seattle Branch of the National Archives of the United States. Established in 1969, the Seattle Archives Branch is one of 11 branches which preserve and make available for research those U.S. Government records of permanent value created and maintained by Federal agencies. The Seattle Branch serves the states of Alaska, Idaho, Oregon, and Washington. The textual and microfilmed records identified in this guide contain basic documentation for the study of subjects such as history, economics, public administration, political science, law, ethnology, and genealogy. Records are listed according to six categories: U.S. Government--General, Legislative Branch, Judicial Branch, Executive Branch, Records of or Relating to Other Governments, and Other Holdings. Executive Branch holdings comprise the bulk of the guide. They include records from the Departments of State, Treasury, Defense, Justice, Interior, Commerce, Labor, and Transportation. Information is given concerning limited loan arrangements. The guide can serve as a model for others who want to develop a handbook of their holdings. (Author/AV)
