Part of the Northern Illinois University Library pages, this site presents many of Lincoln's documents, letters, and speeches electronically.  With options to browse or search these materials with a variety of specifications, the site facilitates quick and easy Lincoln research.  Among its other attributes are bibliographies for Lincoln topics of study, a special page on the Black Hawk War (particularly useful in my research), and an online version of the Lincoln/Barrett text, Life and Public Services of Hon. Abraham Lincoln, which is otherwise available only at the University of Illinois Urbana History Lincoln Room.
 

             The online version of The Collected Works of Abraham Lincoln by Roy P. Basler, an authoritative compilation of Lincoln's documents.  The page proudly advertises the fact that Basler's collection "represented the first major scholarly effort to collect and publish the complete writings of Abraham Lincoln, and the edition has remained an invaluable resource to Lincoln scholars."  This massive, eight-volume collection can be easily navigated through the site's various search functions.
 

            This site possesses a wealth of links to other valuable Lincoln sites, as well as a substantial amount of data about Lincoln.  The photos, virtual tours, links to museums and contemporary essays about Lincoln make the site interactive and fun.  The site also has a page on the Stillman's Run battle of the Black Hawk War and a useful rebuttal to Lerone Bennett Jr.'s thesis that Lincoln's vision for America was a "white dream."
 

            This site is a massive archive of historical documents and photographs from the Library of Congress.  The search functions for historical material at this site are an invaluable resource to any student of American history.  Especially useful for my purposes is the Abraham Lincoln Papers page, an archive of over 20,000 Lincoln documents, many of which are scanned originals.
 

             Though the site in general is focused on African-American history, this page presents a valuable synopsis of westward expansion explained in terms of Frederick Jackson Turner's "frontier theory" and racial/cultural conflict.  The site also has pages on Indian Removal and the Trail of Tears.
 

            A page provided by the University of Missouri Kansas City Law School, this site provides excellent coverage of the 1862 Dakota Conflict in general, in addition to its legal focus on the trial and execution of Indian rebels.  A special treat is a digital reproduction of the original document signed by Abraham Lincoln ordering the excecution of 38 Indians and granting clemency to 265 others.
