The P.K. Yonge Library, in the Department of Special Collections, contains regional histories of Florida that may be of use as background information for your paper topics. A sample list of reference works and local histories is given below. This is a partial list and you can find other titles in LUIS.
You can also search the library catalog, using "Basic Search, Browse Organized Lists" and the following information:
Title begins with: Black studies research sources (useful; brings up 21 microfilm collections)
Title begins with: Research collections in labor studies
Title begins with: Research collections in womens studies
Title begins with: Papers of the NAACP
Subject, LC: African American newspapers
Newspapers can be another good source of information and I can help you with newspaper research. As I noted in the orientation, we have relatively few complete runs of newspapers edited by African Americans but the Colored Citizen (Pensacola) and the "Colored People Here and Elsewhere" section of the Metropolis (Jacksonville) are useful for the period 1900-1920.
See me or one of the other librarians for information on microfilm collections.
