Who Built America? to Become OER with Revamped History Matters Content

With funding by the National Endowment for the Humanities, RRCHNM is partnering with the American Social History Project (ASHP) at the City University of New York on Who Built America? Working People and the Nation’s History. This project creates an updated, completely free, open education resource (OER) and continues a 38-year effort to make social and labor history accessible to the broad public — a core commitment of Roy Rosenzweig’s.

The project will update content from the History Matters website, developed by RRCHNM in 1998, including over 1,000 annotated primary sources in the site’s Many Pasts section and vital historical thinking resources in Making Sense of Evidence. The updated site will supplement the 2-volume Who Built America? textbook and ASHP’s varied multimedia teaching resources from the Who Built America? CD-ROMs to create the free online textbook. The new Who Built America? site will guarantee that the highly used History Matters resources will continue to be available and sustainable in the future for teachers and students of U.S. history.
