This collection of about 300 biographies joins the 500 of the first volume in the series, continuing the project to gain recognition for the accomplishments of men like Archie Alphonso Alexander, whose large-scale engineering projects included airfields, Todd Duncan, whose opera career included leading roles and the mentoring and teaching of dozens of singers, and Lewis Sheridan Leary, who never lived to see his dream of abolition. Entries also include period photographs and illustrations, chronologies and references including print and online resources and, when available, collections of primary documents. The geographic, occupation and subject indices are particularly well done. Annotation ©2007 Book News, Inc., Portland, OR (booknews.com)
