This massive mega-website presents thousands of documents and images related to Missouri's social, political, and economic history, linking to collections housed at universities, libraries, and heritage sites across the state. These resources are organized both into archival collections (by topic and source type) and virtual exhibits.

Archival collections include maps, municipal records, government and political records, newspapers, photographs and images, books and diaries, as well as topical collections on agriculture, medicine, women, business, exploration and settlement, art and popular culture, and family, rendering the website's resources as useful for genealogists as for those interested in history.

Exhibits encompass a diverse range of subjects, and include topics of relevance to Missouri history (Miss Carrie Watkins's cookbook from the mid-19th century, several exhibits on life at the University of Missouri and Washington University, Truman's Whistle Stop campaign), and topics outside of Missouri (the body in Medieval manuscripts, Roman imperial coins, propaganda posters from World War II, and drawings documenting dinosaur discovery before the mid-20th century).

Teachers will be especially interested in the large Education section, which includes curricular resources on topics such as African Americans in Missouri, Lewis and Clark's Expedition, Missouri State Fairs, and the history of dueling.

More than 137,000 photographs of Florida, many focusing on specific localities from the mid-19th century to the present, are available on this website. The collection, including 15 online exhibits, is searchable by subject, photographer, keyword, and date.

Materials include 35 collections on agriculture, the Seminole Indians, state political leaders, Jewish life, family life, postcards, and tourism among other things. Educational units address 17 topics, including the Seminoles, the Civil War in Florida, educator Mary McLeod Bethune, folklorist and writer Zora Neale Hurston, pioneer feminist Roxcy Bolton, the civil rights movement in Florida, and school busing during the 1970s.

"Writing Around Florida" includes ideas to foster appreciation of Florida's heritage. "Highlights of Florida History" presents 46 documents, images, and photographs from Florida's first Spanish period to the present. An interactive timeline presents materials—including audio and video files—on Florida at war, economics and agriculture, geography and the environment, government and politics, and state culture and history.

This ongoing project was designed to present materials on the historical experiences of those with disabilities. The website currently presents nearly 800 documents and more than 930 still images dating from the late 18th century to the present.

Subjects are organized according to categories of advocacy, types of disability, government, institutions, medicine, organizations, private life, public life, and personal names. Documents include articles, poems, pamphlets, speeches, letters, book excerpts, and editorials.

Of special interest are documents from the Roosevelt Warm Springs Institute for Rehabilitation Archives, including the Polio Chronicle, a journal published by patients at Warm Springs, Georgia, from 1931 to 1934. Images include photographs, paintings, postcards, lithographs, children's book illustrations, and 19th-century family photographs, as well as postcard views of institutions, beggars, charity events, and types of wheelchairs.

This website traces the history of the Chicano/a movement in Washington State, which had its roots in the early 1960s when campaigns surrounding farm workers' rights in eastern Washington and community and educational rights in western Washington united and student activism grew at the University of Washington, continued through the 1970s, fractured in the 1980s, and recently reemerged as a younger generation of activists have mobilized around affirmative action, globalization, the Afghanistan and Iraq wars, and immigrant rights.

This website presents a wealth of primary sources documenting this rich history, including 17 oral history interviews with prominent members of activist groups; 73 images of demonstrations, prominent leaders in the movement, and Seattle-area murals; 42 documents, including copies of the "Boycott Bulletins" that keep students informed of the proceedings of the 1969 grape boycott at the University of Washington and documents surrounding the University of Washington's Chicano/a activist group; as well as more than 300 newspaper articles from the University of Washington Daily, the Seattle Times, and the Seattle Post-Intelligencer dating from between 1968 and 1979 and covering topics such as farmworkers and the grape boycott, arts and culture, and the community activist group El Centro de La Raza.

A slideshow providing historical background and highlighting some of these materials is a good place to begin for those unfamiliar with the Chicano/a movement history, as is an extensive timeline and several historical background essays.

This website is part of the larger Seattle Civil Rights and Labor History Project, which provides materials that can serve as larger historical context, such as a guide to civil rights groups from the 1910s to the 1970s, and 14 2,000-word essays on the ethnic press in Seattle.
