Gr 4-8-These clearly written texts are accompanied by numerous reproductions of handbills, maps, period photographs, portraits, political cartoons, the National Republican platform of 1860, blueprints, and letters. For those that are difficult to read in their original format, transcriptions are provided in text boxes or in the appendixes. Each slim volume begins with a time line covering significant dates. The authors do gloss over controversial aspects of the Westward Expansion, and remind readers that such progress was made at the expense of Native Americans, the buffalo, the Californios, and immigrants. The financial scandals surrounding the handling of investments in the Central Pacific Railroad are presented in detail, as is the suspicious creation of Credit Mobilier to handle Union Pacific Railroad stock. Both books are important additions to collections of American history and will be useful to students and their teachers.-Ginny Gustin, Sonoma County Library System, Santa Rosa, CA Copyright 2003 Reed Business Information.
