I wonder how many of the errors were informational and how many were typographical.

Back in college one of my professors used the new unpublished version of his book as the class text. It has been through the editorial process with him and his publisher, including copyediting and his review of galley proofs. He offered us $.25 for the first report of a typo and $1 for the first report of any factual error and by the end of the quarter we found something like 2000 errors in total but only about 30 factual errors.

And then there's the question (and I know I'm taking this way too seriously for what was essentially a "isn't the world silly stupid sometimes" story) of counting methodology. Say they did a last minute edit to the Chapter 12 introduction, shortening it by one page but failed to refresh the index so now half of all the index references are off by one page. Is that 1 error or 873?
