The Manning book page doesn't have any visible links to an Errata page; however, that's where the two errata list links I found mentioned in the book forum redirect to.

"The current errata list can always be found at http://www.manning.com/logan/excerpt_errata.html (or go to http://www.manning.com/logan/ and follow the link named "Errata", under Resources/Look inside)."
