The sixth edition of this series will update each entry on every state in the U.S., including the District of Columbia, Puerto Rico, and the U.S. Caribbean and Pacific dependencies. Entries cover the geography, history, politics, economy and other facts about each state. Alphabetically arranged entries feature consistent subheadings for each state so students can quickly find comparative information. An index of people, places and subjects makes searches easy, and sources for further study provides students with the next step to learn more.
