An edition and a printing are different things. There are multiple printings of the second edition. You have the second edition if the cover looks like the image on the left side of this page. To determine which printing of the second edition you have, look at page iv, which is the copyright page just before the Table of Contents. If the bottom line on the page is a sequence of numbers counting down from 20, printed in a sans-serif font, then the last number on that line is the printing number. Otherwise, find the line around the middle of the page reading ``© 2001 by The Massachusetts Institute of Technology''. If you have the first printing, the line above this copyright line is blank. If you have any printing after the first, the printing number is indicated on the line above this copyright line.
