Web de Anza presents material relating to Juan Bautista de Anza's two expeditions into Alta California that resulted in the settlement of San Francisco in 1776. The site is under development, but it is easy to navigate. Visitors will find a 700-word background essay on the historical context of the expeditions and links to seven other sites about de Anza and California history. Primary source material currently includes eight diaries and two letters, available in English and Spanish and indexed by date. This material is supplemented by a gallery of 11 portraits, 14 images of scenery relevant to De Anza's expeditions, and drawings and photographs of nine objects such as a musket of the kind that De Anza probably used.

The site also includes six photographs of re-enactments of events in de Anza's expedition. An Atlas section provides 10 trail route maps, and 20 maps of the area of de Anza's expedition. The site provides useful material for students of California history, religion, and Native Americans at every level, from elementary to graduate school.

This collection of 30,000 historical photographs contains scenes of San Francisco from 1850 to the present and includes views of streets, buildings, and neighborhoods, as well as photographs of famous San Francisco personalities. Visitors can search for photographs by neighborhoods using the interactive map, one of the site's most engaging options. There are also miniature tours of such locales as the Barbary Coast, Nob Hill, and Telegraph Hill.

The San Francisco neighborhoods are searchable through a list of subjects, which includes monuments, nightclubs, orphanages, parks, and stadiums.

There are several specialized collections, such as the James A. Scott Collection featuring 27 pairs of "before-and-after" images of the city with the photographer's notes and comments.

A photo morgue of the daily newspaper, San Francisco News-Call Bulletin, dating from the 1920s to 1965, completes the site.

These four collections of data and documents address Federal Indian policy in the late 19th century. The first set includes eight annual reports of the Commissioner of Indian Affairs from the 1870s, along with appendices and a map. The second set, Allotment Data, traces the Federal "reform" policy of dividing Indian lands into small tracts for individuals—a significant amount of which went to whites—from the 1870s to the 1910s. This set includes transcriptions of five acts of Congress, tables, and an essay analyzing the data.

The third set includes 111 documents on the little-known Rogue River War of 1855 in Oregon, the reservations set up for Indian survivors, and the allotment of one of these reservations, the Siletz, in 1894. The fourth set provides the California section of an ethnographic compilation from 1952.

These varied collections document the history of Los Angeles and southern California. "Digital Archives" offer more than 126,000 photographs, maps, manuscripts, texts, and sound recordings in addition to exhibits. Nearly 1,200 images of artifacts from early Chinese American settlements in Los Angeles and Santa Barbara are available, as is the entire run of El Clamor Publico, the city's main Spanish-language newspaper from the 1850s. Photographs document Japanese American relocation during World War II and photographs, documents, and oral history audio files record Korean-American history. The archive also includes Works Projects Administration Land Use survey maps and Auto Club materials. A related exhibit, "Los Angeles: Past, Present, and Future", offers collections on additional topics, including discovery and settlement, California missions, electric power, "murders, crimes, and scandals," city neighborhoods, cemeteries, Disneyland, African American gangs, and the Red Car lines.

Access is provided through nine galleries, each containing an introductory essay and 70 to 575 items.

Additional galleries deal with Chinese involvement in U.S. expansion westward; communities outside San Francisco; agricultural, fishing and related industries; the anti-Chinese movement and Chinese exclusion; and sentiments concerning the Chinese. Visitors may search by keyword, name, subject, title, group, and theme. The site will be useful for studying ethnic history, labor history, and the history of the West as well as Chinese-American history.

For those studying the history of the Olympics, sports history, and the history of leisure and recreation, this website provides more than 45,000 documents (in .pdf format) pertaining to official Olympics history as well as other sports.

Diaries documenting the westward treks of 45 men and four women during the period of the California Gold Rush and the westward migration of Mormonism are presented in this site. Although most of these travelers took either the California or Mormon trails, a few diaries provide accounts describing life on trails to Oregon and Montana.

The diaries are complemented by 82 photographs and illustrations in addition to 43 maps, including an interactive map displaying trails, cities, rivers, and landmarks. There are seven published guides, two essays on the Mormon and California trails, brief biographies of most of the diarists, and a list of suggested readings. This is an excellent collection of materials that documents 49 individual perspectives on a movement that encompassed an estimated 500,000 people.

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.

Created to commemorate the 100-year anniversary of the San Francisco earthquake, this exhibit and archive features an extensive collection of primary source material, an interactive map, and a 360-degree view of the damage to the city. The primary sources include thousands of images and text files available, offering more than 8,000 photographs, 500 cityscapes, and 500 letters, as well as a host of additional resources, such as broadsides, oral history texts, periodical articles, photomechanical prints, reports, and stereographs. Visitors can browse the archive by genre or subject or search by keyword, subject, genre, or geographic location.

The exhibit has five galleries, each with several text/photograph displays: San Francisco before the fire; the earthquake; the fire, including a map showing burned districts; the story of refugees and survivors; and reconstruction. The interactive map divides San Francisco into 10 regions, each of which can be browsed or searched for images taken in that region. It also includes 11 aerial cityscape views. The 360-degree panoramic view of San Francisco shortly after the disaster is composed of 11 separate photographs taken from the roof of the Fairmont Hotel.
