The nearly 1,000 maps available on this site document the conflict between Great Britain and America for ownership of the region. They also illustrate the transformation of the physical boundaries of the Pacific region and the efforts of its inhabitants to control the land. The site includes a valuable interactive timeline that presents the maps in historical perspective. The collection contains large-scale geographic maps of the land and sea and small hand-drawn sketches of settlements. The maps are very detailed and most were created in the late-19th- and early-20th-century. Maps are primarily concerned with geography, transportation, climate, population, culture, politics, and tourism and there is a searchable index that is organized according to 21 themes, such as forests, Puget Sound, railroads, Seattle, Washington State University, and Native American reservations.

A drop-down menu allows users to examine and enlarge thumbnail images of each map. Biographical and detailed descriptive text (most between 20 and 500 words) is presented with each image, and the text is searchable by keyword. Created as a resource to help students, teachers and researchers understand the history and development of the state of Washington, this site will appeal to those interested in Washington, historical geography, and the development of cartography.

This collection of essays, commissioned from distinguished scholars, is designed to deepen content knowledge and offer fresh ideas for teaching. Essays begin with a thorough overview of the topic. “Guiding Discussion” offers suggestions on introducing the subject to students, and “Historians Debate” notes secondary sources with varied views on the topic. Notes and additional resources complete each essay. Essays include links to primary sources in the National Humanities Center’s Toolbox Library and are part of the larger TeacherServe project.

Visitors can browse 17 essays, divided into "Native Americans and the Land," "Wilderness and the American Identity," and "The Use of the Land." These focus on the changing ways in which North Americans have related to the natural world and its resources. Topics include, among others, “The Columbian Exchange,” “The Effects of Removal on American Indian Tribes,” “Cities and Suburbs,” and “Environmental Justice for All.”

Useful for teachers looking to expand their content knowledge beyond the information and viewpoints presented in textbooks, and to get a taste of historians' debate over the interpretation of history.

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.

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.

This well-designed site presents the Nebraska edition of the Lewis and Clark journals, edited by Gary E. Moulton.

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.
