Alaska

Gr 4–6—These third editions contain little change from the recently published second editions, with some sections having almost identical texts. Changes include some new information about early Native American populations, energy production and the environment, and seven "Ten Key" facts lists throughout the text about topics such as people, events, cities, animals, and plants. The format is largely unchanged from previous editions, opening with a "Quick Look" at state symbols, followed by an introductory overview and four chapters about the state's history, people, government, and economy. Many of the photos and illustrations have also been retained. This set provides more information than many states series, but some sections haven't undergone significant revision since the first editions, specifically Missouri and Montana. However, Nevada does contain a fair amount of revision.
