America was booming during the second decade of the century, and these volumes cover it all. Entries discuss America’s love affair with the automobile, a “longer” day for urban dwellers made possible by electricity, changes in jobs and earnings due to the millions of immigrants who entered the country at the beginning of the decade, a rise in divorce, and, of course, the Great World War. Every entry focuses on a topic or person during the 1910s that made the decade unique.
