The collection includes 232 unpublished, hand-drafted maps from the years 1899 to 1937. All maps are displayed with original color coding. Users can zoom in and out of maps and can pan right, left, up, or down to examine details. Every map is accompanied by bibliographic data. The full collection can be browsed or the user can choose to browse just the unpublished maps. The collection can be searched by city, year of publication, and county. The maps provide many details about mills and are particularly useful in revealing spatial relationships and location of railroad lines. There is also a link to the Union List of Sanborn and other fire insurance maps. An extremely useful resource for those researching the business or urban history of South Carolina in the decades around 1900.

This site presents the original photographic prints in Alexander Gardner's Photographic Sketch Book of the War. First published in 1865, the Sketch Book was Cornell University Library's seven-millionth acquisition, and they have presented in this site the very best of Gardner's wartime photographs. The book was created by Gardner to recount the history of the Civil War through images and they are displayed in this site with his original descriptive captions. Organized into seven compelling themes, many of the images capture the gruesome reality of war. They include President Lincoln, confederate prisoners, army quarters, soldiers collecting skeletal remains, and a photograph of a dead sharpshooter.

The first section, "The Blank Horror: War and its Victims," consist of seven images, some captured in the immediate aftermath of battle. "Devastated by the Armies: The Changed Landscape" reveals the impact of war on the American landscape, while "Faithful Servants: the Administration of War" shows the government officials behind the war, such as scouts attached to the Secret Service Department of the Army. The monotonous aspects of soldiers' lives are depicted in "The Very Life of Camp" and images within "Advantageous Auxiliaries: Warfare & Technology" focus on how new technologies, such as the telegraph, had an extraordinary impact on warfare during the Civil War. The final sections "To the Memory of the Patriots" and "Gettysburg" are exemplary of the important role Gardener believed he and his colleagues played in recounting the history of the Civil War. Although there is little attempt to interpret the images, those studying the Civil War will find these images striking.

Designed as both an archive and an online exhibit, this site features 3,457 hand-drawn township maps of Illinois. When the government began surveying in 1803 what would later become Illinois, they divided the land into squares six by six miles (36 square miles) called townships. This site includes a 1,000-word introductory history describing the surveying process and introducing the methods and tools of surveyors. Also included here are the maps, available to researchers and the public. A 1,000-word narrative outlines the role of the United States Surveyor General, and traces the custody of these records through the years.

Visitors use a map of Illinois to locate the region and county of the plat they wish to view, and can pan left and right or zoom in and out. A legend helps users decipher early 19th-century symbols. In addition, the site links to an Illinois state website (Illinois Public Domain Land Tract Sales), where researchers can search for the first owners of plats. This site is a great place to view original, early-19th-century maps of Illinois.

For educators, the site includes 20 lesson plans, under such categories as American Heritage and Democratic Process. The classroom activities are well-conceived; they feature problem solving and critical thinking exercises like the Mystery Photo Album, in which students attempt to figure out where in the Cleveland area historical photographs were taken, and By the Neck Until Dead, an e-book that details the history of Cuyahoga County, OH, hangings.
