Cheyenne
2 of the 6 encyclopedias on this shelf carry an entry for Cheyenne. Both are reproduced below, so you can see where they agree and where they differ.
Aiton's Encyclopedia (1910)
shi-en, a western Indian tribe belonging to the same family as the Delawares, Shawnees, Ojibways, and Blackfeet. When first known, they lived on the Sheyenne River in the eastern part of South Dakota . They were driven westward by the Sioux into the Black Hills country. Originally agricultural, they became possessed of ponies and acquired nomadic habits. Their raids extended as far southwestward as the borders of Mexico, and their claim to territory extended from the forks of the Platte to northern Montana. When the whites wanted the country the usual routine of treaties, broken faith, massacres, and extermination was followed. Hancock and Custer were engaged in subduing these Indians. The Cheyennes are physically a tall, well built race. At present there are somewhat over 1,000 of them on a reservation in the Tongue River valley, Custer County, Montana; others, perhaps 2,000 in number, are settled with their relatives, the Arapaho Indians, on the Canadian River in Oklahoma. The name is perpetuated in Cheyenne, the picturesque capital of Wyoming. See Indians
Collier's New Encyclopedia (1921)
city, capital of the State of Wyoming, and county-seat of Laramie co.; on the Union Pacific, the Colorado and Southern, and Burlington Route railroads, 105 miles N. of Denver.

What Has Changed in the Last Century
Aiton's 1910 count of "somewhat over 1,000" Cheyenne in Montana and perhaps 2,000 in Oklahoma marked the low point; today the Northern Cheyenne Tribe in southeastern Montana and the Cheyenne and Arapaho Tribes of Oklahoma each enroll roughly ten thousand or more members, and both run their own governments, courts and colleges. The events Aiton compressed into "the usual routine of treaties, broken faith, massacres, and extermination" now have names taught in American schools — the Sand Creek Massacre of 1864, made a National Historic Site in 2007, and the Cheyenne role in defeating Custer at the Little Bighorn in 1876. The Cheyenne language, correctly placed by Aiton in the Algonquian family alongside Ojibwe and Blackfoot, is now severely endangered and the object of active revival programs. As for the city, Collier's 13,829 people of 1920 have become some 65,000; Fort Russell became F. E. Warren Air Force Base and controls intercontinental ballistic missiles, while the "annual 'round up'" is Cheyenne Frontier Days, still running each July.
