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.

The stated purpose of this website is to provide an overview of World War I. This it does effectively through hundreds of essays, 3,100 encyclopedic entries, 618 biographies, 318 resources on the war's major diplomatic and military events, and a timeline. Primary documents include over 100 diaries and firsthand accounts of soldiers and politicians, 3,900 photographs, 651 propaganda posters, and 155 audio files of songs and speeches. Documents include treaties, reports, correspondence, memoirs, speeches, dispatches, and accounts of battles and sieges.

The site also provides 95 essays on literary figures who wrote about the war. While admittedly a work-in-progress, the site offers much material on the leaders who engaged their countries in war and on the experiences of ordinary soldiers who fought the battles.

On June 15, 1920, a white mob broke into a jail in Duluth, Minnesota, and lynched three black men—Elias Clayton, Elmer Jackson, and Isaac McGhie—accused of raping a white woman. This website tells the story of that attack and its aftermath through more than 700 primary source documents and photographs relating to the lynchings, legal proceedings against members of the lynch mob and several other black men accused of rape, and the incarceration of three white mob members for rioting and one black man for rape. It ends with the aftermath of the incident, including a drop in the black population of Duluth by 16 percent, the formation of an active NAACP chapter in the city, and a campaign for anti-lynching legislation. A Background section sets the scene in 1920s Duluth alongside information on rising racial tensions across the country and lynchings in northern states. An interactive timeline of events surrounding the lynchings, accompanied by an audio narrative, is a good place to begin. All documents are keyword searchable and browseable by document type (government document, newspaper, correspondence) and by date.

The more than 3,500 full-text documents available on this website address the legal, economic, political, diplomatic, and government history of the U.S. Documents are divided into five time periods—pre-18th, 18th, 19th, 20th, and 21st centuries—and include treaties, presidential papers and addresses, and colonial charters, as well as state and federal constitutional and legal documents.

The materials are categorized into 64 document collections as well, such as American Revolution, Federalist Papers, slavery, Native Americans, Confederate States of America, World War II, Cold War, Indochina, Soviet-American diplomacy, and September 11, 2001. By clicking "What's New," the latest digitized documents become available. Material also can be accessed through an alphabetical list of 350 more specific categories, keyword searching, and advanced searching. Most of these documents are directly related to American history, but the site includes some materials on European and modern diplomatic history.

This interactive case study explores the 18th-century diary of midwife Martha Ballard and the construction of two late 20th-century historical studies based on the diary: historian Laurel Thatcher Ulrich's book A Midwife's Tale and Laurie Kahn-Leavitt's PBS film by the same name.

The site provides facsimile and transcribed full-text versions of the 1,400-page diary. An archive offers images of more than 50 documents on such topics as Ballard's life, domestic life, law and justice, finance and commerce, geography and surveying, midwifery and birth, medical information, religion, and Maine history. Also included are five maps, present-day images of Augusta and Hallowell, ME, and a timeline tracing Maine's history, the history of science and medicine, and a history of Ballard and Hallowell. The site offers suggestions on using primary sources to conduct research, including essays on reading 18th-century writing and probate records, searching for deeds, and exploring graveyards. A bibliography offers nearly 150 scholarly works and nearly 50 websites.
