The first ed. was published in Florence in 1561, under the care of the author's nephew Agnolo Guicciardini, and contained sixteen books only; the last four being unfinished, the editor hesitated to publish them and they were not printed until 1564. The present edition was published by Francesco Sansovino and, like the 1st, contains only 16 books, covering the years 1490-1526.

The final 4 books, covering the years 1526-1532, were 1st published with title and imprint: Dell'historia d'Italia ..., gli ultimi quattro libri non piu stampati. Vinegia : G. Giolito de' Ferrari, 1564.--NUC pre-1956.

The 20 books of Guicciardini were continued by C.G.G. Botta in his "Storia d'Italia continuata da quella del Guicciardini sino al 1789".--OCLC OLUC.
