This archive offers a collection of more than 900,000 photographs, maps, letters, documents, books, artifacts, and other items relating to all aspects of Texas history, from prehistory through the 20th century. Subjects include agriculture, arts and crafts, education, immigration, military and war, places, science and technology, sports and recreation, architecture, business and economics, government and law, literature, people, religion, social life and customs, and the Texas landscape and nature. Some subjects include sub-categories. For instance, social life and customs, with 694 items, includes 13 sub-categories, such as clothing, families, food and cooking, homes, slavery, and travel. The visitor can also search the collection by keyword.

Resources for educators include seven "primary source adventures," divided into 4th- and 7th-grade levels, with lesson plans, preparatory resources, student worksheets, and PowerPoint slideshows. Subjects of the lessons include Cabeza de Vaca, Hood's Texas Brigade in the Civil War, life in the Civilian Conservation Corps, the journey of Coronado, the Mier Expedition, runaway slaves, the Shelby County Regulator Moderator war, and a comparison of Wichita and Comanche village life. This website offers useful resources for both researching and teaching the history of Texas.

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.

Emma Goldman (1869–1940) was a major figure in the radical and feminist movements in the United States prior to her deportation in 1919. This collection of primary resources includes selections from four books by Goldman as well as 18 published essays and pamphlets, four speeches, 49 letters, and five newspaper accounts of Goldman's activities.

There are also nearly 40 photographs, illustrations, and facsimiles of documents. Additional items include two biographical exhibitions, selections from a published guide of documentary sources, and four sample documents from the book edition of her papers. A curriculum for students is designed to aid the study of freedom of expression, women's rights, anti-militarism, and social change. The site offers essays on the project's history and bibliographic references as well as links to other websites.

This website provides free access to a variety of visual materials and "seeks to illustrate the unique role of visual images in American history." Clio is an educational organization developing American history projects with appeal to a wide audience, including students, educators, and researchers. This site aims to not only provide access to a variety of visual historical materials, such as photographs, illustrations, and material objects (namely quilts), but also "to promote visual literacy by exploring the variety of ways that images enhance our understanding of the past and challenge us to hone our interpretive skills."

The website is organized into three main sections. The first, "Visualizing America," includes two collections of modules, titled "Picturing the Past: Illustrated Histories and the American Imagination, 1840–1900," and "Quilts as Visual History." A second section, ”Photography Exhibits," includes three photography collections: one focusing on the work of Frances Benjamin Johnston, another on the work of the Allen Sisters (Mary and Frances Allen), and the Peter Palmquist Gallery. A third section, "Creating History," examines the figure of Lowell Thomas, who became one of America's best known journalists, as well as the media version and reality of Lawrence of Arabia.

An additional section concerning women's history and lives in the 21st century and second half of the 20th century is planned for 2013.

A valuable website to students and researchers alike, it suffers only slightly from a lack of search capabilities.

The 190 works presented on this site—approximately 40,000 written pages and more than 3,000 illustrations—provide eyewitness accounts covering California history from the Gold Rush through the end of the 19th century. Most authors represented are white, educated, male Americans, including reporters detailing Gold Rush incidents and visitors from the 1880s attracted to a highly-publicized romantic vision of California life.

The narratives, in the form of diaries, descriptions, guidebooks, and subsequent reminiscences, portray encounters with those living in California as well as the impact of mining, ranching, and agriculture. Additional topics include urban development, the growth of cities, and California's unique place in American culture. A special presentation recounts early California history, and a discussion of the collection's strengths and weaknesses provides useful context for the first-person accounts.
