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.

Post-Civil-War industrialization and urbanization put new stresses on American law and society. Criminal records reveal the circumstances where social strain boiled over into violence and unrest. Using this website, visitors can search the complete Chicago Police Department Homicide Record Index from 1870 to 1930, detailing more than 11,000 homicides, and read and watch accompanying contextual material that explores tensions between laborers, industry leaders, political ideologies, social reformers, organized crime, and more.

The core of the site is the "Interactive Database." Here, visitors can search cases using keyword, case number, date, circumstances (accident, manslaughter, homicide, number of victims, number of defendants, method of killing, involvement of alcohol), details about the victim and defendant (age, gender, race, occupation), victim/defendant relationship, and legal outcome. Searches return one-line case summaries including the date, names of people involved, case number, a description of the crime, and legal outcome. Clicking on a result brings up details on the particular crime: time, location, type of death/homicide and details of homicide, details on the victim(s) and defendant(s), police involvement, and legal outcome.

Contextualizing primary and secondary sources frame this bare-bones information. A timeline features a summary of one major event and up to five photographs for every year. "Historical Context" currently offers a second timeline highlighting links to up to 17 notable cases for each year and a section on children's lives in the city, with nine newspaper articles on child labor and obituaries for activist Florence Kelley and lawyer Levy Mayer. (Sections on labor and reform movements and people and events did not work at the time of this review.) In "Legal Content," visitors can read short essays on topics related to Chicago criminal and social history, including capital punishment, anti-corruption campaigns, the Chicago Police Department, judges, lawyers, criminology, prostitution, gambling, murder-suicides, and accidents. Each essay links to related cases and onsite and off-site documents. "Legal Content" also hosts 16 downloadable acts and statutes under "The Laws."

"Crimes of the Century" organizes links to related cases under 23 topics, including the 1919 Chicago race riot and the Haymarket Affair. "Publications," the most valuable part of the site for teachers looking for primary sources, archives the full text of 15 primary and secondary documents related to Chicago crime and social change. Here users can download in PDF form modern studies on the death penalty, crime and policing in Chicago, and the Haymarket Affair, or download primary sources such as law codes and crime reports, the Hull House Maps and Papers, Chicago Daily News articles exposing graft and corruption, 19th-century studies of Chicago's homeless, and contemporary commentary on the Haymarket Affair. Finally, visitors can watch 18 interviews with present-day professors, judges, and lawyers in "Videos."

Though difficult to navigate, this site has rich resources to help students and teachers explore the challenges of change at the turn of the century.

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.

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.

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.

Created in anticipation of the 50-year anniversary of the monumental Supreme Court decision, Brown v. Board of Education, this website covers four general areas. These include Supreme Court cases, busing and school integration, school integration in Ann Arbor (home of the University of Michigan), and recent resegregation trends in America. The site contains a case summary and the court's opinion for each of 34 landmark court cases, from Plessy v. Ferguson to Brown v. Board of Education of Topeka.

Brown includes transcripts of oral arguments, as well. Visitors can also read the oral histories of five members of the University of Michigan community who remember the Brown decision and its impact. There are more than 30 photographs of participants in the Brown case and other civil rights activists, as well as a collection of documents pertaining to desegregation in the Ann Arbor Public School District. A statistical section details the growing number of African Americans in Michigan and Ann Arbor schools from 1950 to 1960.
