Scanned images of more than 18,000 pieces of sheet music, including covers, published prior to 1923 are presented on this website. The collection, compiled by an American musicologist, covers the period 1780–1980 but focuses on 19th-century popular music, especially songs relating to military conflicts, presidents, romance, transportation, and songs from the minstrel stage.

Users may search for songs on hundreds of topics such as drinking, smoking, fraternal orders, the circus, and death, or look for composers, song titles, or other catalog record data. Descriptions by the collector of significant songs in 38 topical categories are also available. These materials are useful for studying 19th- and early 20th-century popular culture, especially depictions of ethnicity, gender, and race.

These 11 exhibits address the history of California and San Francisco. Topics include the Gold Rush of 1849; earthquakes of 1906 and 1989; the history of the city's fire department; construction of the Golden Gate and Bay Bridges; and the internment of Japanese Americans during World War II. These exhibits provide timelines and links to more than 200 primary documents and images, including newspaper articles, diary entries, oral histories, photographs, political cartoons, and engravings. Two exhibits are hyperlinked chronologies pertaining to San Francisco during World War II and the rock music scene in the city from 1965 to 1969.

Documents can be accessed according to subject, with more than 25 documents listed on the Chinese-American community, fairs and expositions, and labor issues. The site also contains more than 150 biographies of prominent San Franciscans.

This collection presents the complete run—from February 8, 1918 to June 13, 1919—of the "official newspaper" of the U.S. Army fighting forces during World War I. The American Expeditionary Forces (AEF) were formed in May 1917 following U.S. entrance into the war. Stars and Stripes was created by order of the AEF supreme commander, General John J. Pershing, to strengthen morale and promote unity among soldiers. Professionals from the newspaper industry joined the staff, including a few well-known journalists. At its peak, the weekly newspaper reached more than half a million soldiers, providing news of the war, sports reports, cartoons, news from home, and poetry.

A special presentation includes essays on the newspaper's contents, staff, advertising, military censorship, the American Expeditionary Forces, and the role women played in the war effort. Search the full text or browse individual issues.
