This selective bibliography lists books and some dissertations and theses relating to ethnicity. It is intended for junior and senior high school students, undergraduate college students, and the general public. The objective is to help ethnic groups, community agencies, and individuals in Cincinnati locate relevant source material concerning ethnicity and their ethnic heritage. Citations are included on geneology, immigration, and individual ethnic groups. These groups include Afro-Americans, American Indians, Appalachian-Americans, Arab-Americans, Asian-Americans, Dutch-Americans, Eastern European Americans, English and Scottish-Americans, French-Americans; German Americans, Hispano-Americans, Irish-Americans, Italian-Americans, Jewish-Americans, Near and Middle Eastern Americans, Greek-Americans, Scandinavian-Americans, and Swiss-Americans. A brief ethnic historical sketch of greater Cincinnati is also presented. The citations are arranged alphabetically by author and include title, publisher, date, and the library in which they can be found. To be listed, the sources must be in a local library, must be in the English language, and must have been published since 1920. No personal narratives, biographies, books on race relations, religion, civil rights, slavery, or suffrage are listed. An author index and addresses and hours of the libraries are appended. (CK)
