The UW Libraries has an extensive collection of historic newspapers on microfilm housed in the Microform and Newspaper Collections. The best way to identify available newspapers is to use the card catalog in the Microform and Newspaper Collections. You can also search the UW Libraries Catalog for the newspaper. This page includes links to UW restricted digitized historic newspapers and selected freely available digitized newspapers. To find additional freely available digitized historic newspapers see ICON: International Coalition on Newspapers.
For contemporary newspaper coverage (roughly since 1990) see Finding News Articles.
