The second in a series of African-American bibliographies, this bibliography was issued in honor of both Black History Month and Inventors Day in February 1991. It focuses on the contributions of black Americans in the areas of science, technology, medicine, and allied fields such as dentistry and nursing. The materials cited emphasize the accomplishments of individuals from all parts of the United States, in all periods, and from all backgrounds. The bibliography lists items in the collections of the New York State Library and includes books, selected periodical articles, patents, and other materials. New York State Library call numbers are given for the books and periodicals to facilitate both library retrieval and interlibrary loan. Patent documents are filed numerically and are part of the patent depository collection of the New York State Library. It is noted that no more than three patents are given for each inventor for reasons of space. (MAB)
