While the above review did raise some legitimate concerns, this comment is completely out of line. It refers not primarily to the new volume but to an earlier edition. The commenter is not sure whether that was the 5th (1991) or 6th (1999) edition but, whichever, it is said to have been simply a still older version with nothing new except the cover, and with no references more recent than a decade prior to publication. Actually, in the 5th edition, as compared to the 4th (1983) edition, text length was increased by 22 percent, substantive changes were made to about 80 percent of the previously existing generic accounts, and 106 new generic accounts were added. Respective figures for the 6th edition are a 25 percent increase in text length, 95 percent of previous generic accounts substantively modified, and 81 new generic accounts. Those figures can be found in the prefaces, which also indicate that a thorough literature search was made through 1988 for the 5th and through 1995 for the 6th edition. Incidentally, the new (2018) volume cites approximately 2,200 new literary sources, while retaining 1,000 from the 6th edition.
