The George C. Barker collection consists of Barker’s research notes, correspondence and field notes from his research activities. The research notes consist primarily of articles, offprints, newspaper clippings and secondary literature accumulated by Barker during the course of his study and research in bilingualism and folklore. Many items address issues of bilingualism in the southwestern United States, and its social manifestations.

The interviews consist of reel tapes of Pachuco dialogue, songs, and interviews. An edited reel has been made from the original paper tape reel. Personal names have been edited out of this duplicate reel.
