Historical aspects of many of the 384 areas under the National Park Service's stewardship are presented in this expansive site. A "Links to the Past" section contains more than 25 text and picture presentations on such diverse history-related topics as archeology, architecture, cultural groups and landscapes, historic buildings, and military history. Of particular interest to teachers, a section entitled "Teaching with Historic Places" features more than 60 lesson plans designed "to enliven the teaching of history, social studies, geography, civics, and other subjects" by incorporating National Register of Historic Places into educational explorations of historic subjects. Examples include an early rice plantation in South Carolina; the lives of turn-of-the-century immigrant cigar makers near Tampa, Florida; a contrast between the Indianapolis headquarters of African-American businesswoman Madam C. J. Walker and a small store in Kemmerer, Wyoming, that grew into the J. C. Penney Company, the first nationwide department store chain; the Civil War Andersonville prisoner of war camp; President John F. Kennedy's birthplace; the Liberty Bell; Finnish log cabins in Iowa; and the Massachusetts Bay Colony's Saugus Iron Works. Especially useful for teachers interested in connecting the study of history with historic sites.

Presents a narrative in exhibit format—with hyperlinks to archival documents and photographs—on the cultural and economic life of the people who came to the Central Illinois River region from 1875 to 1950. Organized into three sections on the harvesting of fish, waterfowl, mussels, and natural ice; transportation by boat, railroad, and plank roads; and the settlement and development of six area river towns. The site delivers oral histories (audio and video), as well as illustrations and photographs. It may serve as a useful introduction to those studying this particular region and regional history in general.

This site is a collection of 253 travel narratives written between 1750 and 1920. The narratives were written by American citizens and foreign visitors about their travels in America. Some of the accounts were written by famous Americans (James Fenimore Cooper and Washington Irving, for example), but most of the authors were not famous. The narratives include their observations and opinions about American people, places, and society; and are valuable sources for the study of early American attitudes. Most accounts are viewable either as scanned images or as transcribed texts. Also included is the 32-volume set of manuscript sources entitled Early Western Travels, 1748-1846. The collection is searchable by keyword, and may be browsed by subject, author, and title. Students and teachers will find these primary sources invaluable for research and study of the late 18th and 19th centuries.

Visitors to this site are invited to explore historical aspects of the roughly 200 National Park Service locations designated important to U.S. history and prehistory. Materials are organized by "cultural resource subjects," including archeology, architecture and engineers, cultural groups, cultural landscapes, historic buildings, mapping, maritime and military history, and "cultural resource programs," such as the American Indian Liaison Program and Heritage Preservation Services.

Visitors can search for information on more than 2.5 million Civil War soldiers and sailors; more than 71,000 properties listed in the National Register of Historic Places; and approximately 240,000 reports on federal archaeological projects in the National Archaeological Database. National Register Travel Itineraries provide historic guides to 18 cities and communities. The National Underground Railroad Network to Freedom contains information on 51 sites of importance and on slavery and antislavery efforts.

Also of interest are bibliographies on the African American west and public history, and full-text publications on the Antiquities Act of 1906 and the promotion of the city of Seattle during the gold rush era. The homepage—"History and Culture"—presents several topical, comprehensive historical exhibits including the "Eisenhower Virtual Museum."
