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.

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.

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.
