This month’s cover features a 1992 photograph of Castillo pyramid and columns representing Mayan warriors at Chichen Itza from the Payne B. Johnson Collection at the University of Southern California (USC) Libraries’ Special Collections.

With support from the Council on Library and Information Resources under the Digitizing Hidden Collections grant program, Cal State LA and the USC Libraries are partnering on a project to digitize cultural artifacts, rare books, and photography collections that document Mesoamerican cultures and early contacts with and representations of Indigenous cultures in present-day Mexico and Central America. Included in the project are more than 25,000 historic photographs of Mesoamerican cultural sites from both universities’ archival collections.
