Digital collections of Civil War era newspapers are great resources and are available at a number of different sites. One that I want to highlight is UC Riverside’s California Digital Newspaper Collection, which includes the Daily Alta Californian (1849-1891) and the Sacramento Daily Union (1856-76). Each issue can be downloaded as a PDF file. Several lesson plans are also available on the site.
Teachers may also want to check out the USC Digital Library. This site offers several newspapers, including the Los Angeles El Clamor Publico (1855-1859) and the Los Angeles Star (1851-1864). Thousands of historic maps and images, such as California’s first State House, can also be downloaded.
