What essential reading material (text books) are recommended for political science, history, chicano studies, and economics for college undergrads??

ADDITIONAL INFO: major texts are fine, as well as nonfiction, and I'd love to hear from radical perspectives (preferrably from the most respected and lucid radical authorities of said subjects). By History, I mean the history of the U.S.. I'd say Political science, history, and Chicano studies are my top priorities.

THANK YOU!!!
