This website overviews the early history of the U.S. Parcel Post system. Although the website states that it examines “one hundred years of parcels, packages, and packets,” most of the content is from the first few years of the service, 1913 through 1915. An introduction and six subsections—Congressional Opposition, The First Packages, The Oddest Parcels, The Service in Use, Preparing for All of Those Packages, and A Century of Posted Parcels—feature short essays and 25 photographs and cartoons.

Though the website is text-heavy, teachers could potentially use its resources with students to examine early 20th-century United States history or changes in communication within the United States.

This website provides a light introduction to the history of Prohibition in the United States, reinforced with videos and images from the Ken Burns and Lynn Novick documentary from PBS. The website showcases a photo gallery and biographies on figures from the time period paired with clips from the full-length documentary. The website also includes a map and timeline function for visualizing Prohibition efforts across space and time, as well as more than 10 lesson plans and activity resources for educators.

The website is relatively easy to navigate. The photo gallery contains more than 70 images of individuals, newspaper articles, and events, coupled with brief descriptions. More than 30 brief videos, pulled from the larger documentary, are scattered throughout the website. (Note: the video content is not transcribed or captioned.) Another useful feature may be the map, which enables visitors to get a sense of the geographical relationship of events and figures, or the timeline, which visualizes the sequence of events. Students may also be encouraged to examine one of the more than 20 biographies: brief descriptions paired with videos that provide a more in-depth discussion of the individual.

Educators should direct their attention to the For Educators section. This page provides access to four prepared lesson plans and nine quick "snapshot activities" intended to work in conjunction with website and documentary materials. These activities can be modified and integrated into larger units in coursework on these subjects. Given the graphic nature of some photos on the site and the available subject content, teachers may want to reserve the website for students grades eight and higher.

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.

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.

Provides 55 images and 60 short essays, ranging in length from a few sentences to approximately 1,500 words, on significant topics in the history of American education. The essays were prepared by undergraduates and edited by their professor, Robert N. Barger, who holds a Ph.D. in the history of education. Organized into five chronological categories from the colonial era to the present, with an additional essay on European influences. Covers such topics as hornbooks, primers, McGuffey Reader's, normal schools, kindergarten, high school, African-American education, adult education, prayer in schools, student rights, and education of the handicapped. Includes essays on such personages as Freidrich Froebel, Herbert Spenser, Benjamin Franklin, Thomas Jefferson, Benjamin Rush, Horace Mann, and G. Stanley Hall. Also offers information on recent topics such as the Committee on Excellence in Education's 1983 study, A Nation at Risk, and the Goals 2000: Educate America Act, signed into law in 1994. Professor Barger's warning that he did not add balance to the "triumphalist" perspective that some of his students adopted should be remembered by those using this site. Nevertheless, it provides a useful introduction to high school students and undergraduates studying the history of American education.

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.
