American National Biography
"Over 10 years in the making, American National Biography is a fascinating study of the people who have shaped the United States. Why replace the Dictionary of American Biography instead of merely updating it through supplements? Because the editors include new scholarship and people who were missed in the original, especially women and ethnic minorities. Numbering 24 volumes and containing 17,500 entries, the work offers readable, informative, and critical biographies for each subject, the location of their papers (if they exist), and selective bibliographies. Excellent indexes--subject, contributor, place of birth, and occupation--enhance use. This is an outstanding set that will be heavily consulted for many years to come."--"Outstanding reference sources 2000", American Libraries, May 2000.
