# The printing number of a book

When Stata makes changes to a book or manual, we change the printing number (the ISBN remains the same). You can determine the printing number of a book by looking on the page that gives the ISBN, copyright notice, etc. (one of the first pages in the book). You will find a line with numbers counting down from ten. The number at the end of this line is the printing number. So, for instance, the first printing of a book would have a line like this:

    10  9  8  7  6  5  4  3  2  1


The third printing would have a line like this:

    10  9  8  7  6  5  4  3
