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.

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.
