When searching for primary and secondary sources online, look for websites with high quality information, like government agencies (i.e. .gov websites) or online repositories or exhibits from a museum, university, or organization dedicated to arts education. Also look for sites that provide references, so you can track down further information on topics of interest! Below are websites where you can search for research on American art, or the work of art itself!
Listed are inventories (PDF) to collections in Archives and Special Collections that may contain helpful sources on the WPA prints. You will need Adobe Acrobat Reader to open the documents, which is freely available online.
