Social studies instructors will find a wealth of powerful resources relating to nineteenth and twentieth century U.S. History on HERB, a database created by the American Social History Project (ASHP)/Center for Media and Learning (CML) at the City University of New York. Named after labor historian Herbert Gutman (co-founder of ASHP/CML), HERB offers provocative primary sources, accessible secondary source material, and a variety of interactive classroom activities, including role plays, debates, group projects, and reading and writing activities. The Collections are perhaps the best way to browse the HERB resources. These include Slave Communities & Resistance, Building the Railroads, and Heaven Will Protect the Working Girl. Resources are also organized into ten Historical Eras, beginning with Three Worlds Meet (to 1620) and ending with Contemporary U.S. (1976 to the present). In keeping with the mission of ASHP/CML, these resources are designed to help students understand how "everyday" individuals shaped U.S. history.
