The books included in this bibliography were written by or about notable Americans from the 16th century to the present and were selected from the holdings of the Penfield Library, State University of New York, Oswego, on the basis of the individual's contribution in his field. The division into subject groups is borrowed from the biographical section of the "Encyclopedia of American History" with the addition of "Presidents" and includes fields in science, social science, arts and humanities, and public life. A person versatile in more than one field is categorized under the field which reflects his greatest achievement. Scientists who were more effective in the diffusion of knowledge than in original and creative work, appear in the tables as "Educators." Each bibliographic entry includes author, title, publisher, place and data of publication, and Library of Congress classification. An index of names and list of selected reference tools containing biographies concludes the bibliography. (JH)
