This directory of library materials vendors is designed for use by medium-sized public libraries to assist librarians in developing collections for the multicultural, multililgual cmmunities which they serve, and includes information on vendor profile, pre-order services provided, and customer satisfaction. The directory concentrates on four major groups in California: Asian American--of Chinese, Japanese, Korean, Pilipino and Vietnamese descent; Black; Chicano/Spanish-speaking; and Native American. An ethnic vendor is anyone who supplies materials about the history and culture in English or in the languages of the particular group or groups, whether exclusively or as part of his stock. A machine-readable questionnaire and letter were sent to 430 vendors and 100 libraries and library systems throughout California. The 140 vendor and 23 library responses were tabulated for a print-out including 61 comparative data responses (self-evaluation by the vendor plus at least one library evaluation); 79 vendor-only responses; and 41 vendors evaluated by at least one library. A subject index provides vendor names as sources of: (1) generalized Asian American materials in English; (2) materials in the Chinese, Japanese, Korean, Pilipino, and Vietnamese languages; (3) Black materials; (4) Chicano/Spanish language materials; and (5) Native American materials.
