How to Find Information on the Lewis and Clark Expedition: A Pathfinder

This guide will introduce some of the resources available on the LEWIS & CLARK EXPEDITION OF 1804-1806. The various types of library materials useful in research are described along with some examples of each type. This guide is not a comprehensive listing of sources, but is intended to be a starting point from which readers can begin their research according to their specific needs.


There are a number of primary and secondary sources on the expedition. Primary sources include:

  • History of the Expedition under the Command of Lewis and Clark, to the sources of the Missouri River, Thence across the Rocky Mountains and down the Columbia River to the Pacific Ocean, performed during the years 1804-5-6/ by order of the government of the United States.

To find other titles that may be in CARL's collection, search the CARL Online Catalog. Use the subject keywords: Lewis Clark Expedition.


These resources will provide citations to articles and reports on specific topics. Some journals also have their own consolidated indexes and can be a valuable source for information. These online sources are available from Fort Leavenworth or CARL computers.


A few of the many on military history, these sites have both good content and links to other sites.
