The California Migrant, Transient, and Homeless Populations collection consists of article offprints, booklets, unpublished papers, transcripts of hearings, newspaper clippings, one book, and twenty-two photographs spanning the years 1930-1992. All items in this collection (in one form or another) concern the rootless in society; especially prominent in these holdings are materials concerning migrant farm workers principally in California, but also in other parts of the nation. Other areas of interest are the homeless and transient youths. The "Cotton Survey" (1938) examined the living conditions of migrant farm workers and contains invaluable black-and-white photographs of farmers' camps in such places as Kern County. Also noteworthy are transcripts of testimony from Carey McWilliams, the famous editor of The Nation and authority on California ethnic groups, before state hearings on the migrant worker. The collection also contains an assembly of reports and papers from various private and public agencies on the homeless problem of the 80s and the 90s.
