On the bottom of the copyright page (facing the first page of the table of contents), look for a line such as
First printing, January 2014
In the errata below, we indicate the printing in which the error has been fixed inside square brackets such as [4].
For example, suppose you have the fourth printing. Then you can ignore all reports that are prefixed with [2], [3] or [4]. But you would want to pay attention to all reports that are prefixed with [5] or higher or that have no bracketed prefix at all.
