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.

The Milwaukee Art Museum's collection includes more than 20,000 works of art ranging in date from antiquity to the present, and specializing in American decorative arts, German Expressionism, Haitian art, and American art after 1960. This website presents more than 200 pieces from the museum's collection. These works include paintings and sculptures, including several 20th-century works from Haiti; photographs, including Civil War-era portraits and masterpieces from the Great Depression era; prints and drawings primarily from French, Italian, German, and Flemish artists in the 17th-19th centuries; and a small collection of decorative arts, primarily furniture pieces from the early United States.

Beyond the website's Collection section, more artwork is on display in the Exhibitions section, which includes a selection of images from more than 25 current and past exhibitions. A highlight is the exhibit dedicated to the groundbreaking work of Milwaukee industrial designer Brooks Stevens. Here, visitors can view detailed images of some of his most famous designs, which include the Miller Brewing Company logo, the Evinrude outboard motor, and the Oscar Meyer Weinermobile.

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.
