How to Tell which Printing You Have

On the bottom of the copyright page (facing the first page of the table of contents), look for a line such asFirst printing, April 2008

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 wouldwant to pay attention to all reports that are prefixed with [5] or higher or that have no bracketed prefix at all.
