This short volume is a condensed, rewritten, updated, and otherwise considerably revised version of The United Combined Edition, Seventh Edition. It reflects a division of chronological interest on the part of the two authors, with Jordan's interest being in early American history through the Civil War, and Litwack's during and since that revolutionary event to the present.
Leon Frank Litwack was an American historian whose scholarship focuses on slavery, the Reconstruction Era of the United States, and its aftermath into the 20th century. He received his BA in 1951 and Ph.D. in 1958 from the University of California, Berkeley, and taught the University of Wisconsin, University of South Carolina, Louisiana State University and Colorado College before assuming a position at UC-Berkeley, where he taught until his retirement in 2007.
