(28.5 cm), cclxxi, 433 pp. Publisher’s cloth, original plain card slipcase. - Lists all the Machiavelli editions from the first edition of the Decemnale (c. 1506) to an Arabic version of “The Prince” in Cairo in 1911, with pertinent details, including locations of extant copies (the holdings of 700 libraries in thirty countries were investigated). Of the 1080 entries, 220 are of sixteenth-century books, about 140 of seventeenth-century and about 175 of eighteenth-century books. The lengthy introduction (262 pages) explains how and why many of the editions mentioned in the bibliography actually reached the press. Although there has been criticism of certain bibliographical procedures (see comments by Roberto Ridolfi and by Clementina Rotondi, in La Bibliofilia, volume 82, 1980, pp.75-84), there can be no doubt about the authors’ thoroughness. Issued as volume X of Machiavelli’s Opera Omnia. Cf.
