The Cheyennes ($15.95; Sept. 15, 1996; 32 pp.; 0-8234-1250-4): This entry in the First Americans series (The Hopis, 1995, etc.) follows the fine format established by Sneve and Himler, incorporating cultural facts and historical events under headings: ``Men,'' ``Women,'' ``Children,'' ``Moving West,'' ``Southern Cheyennes,'' ``Northern Cheyennes,'' etc. The jacket painting harks back to images of the ``warrior'' Cheyennes from old movies and TV programs. The surprise, then, is the unfolding of information inside that fleshes out the images and counters the stereotypes. The acknowledgments include bibliographic information. (maps, index) (Picture book/nonfiction. 6-9)
