(Somehow, I never got around to announcing this here, but this page has actually been up for nearly a month.)
I recently got a notification of one or two new ones, which I haven't yet integrated. These will be, soon. The errata is also provided as a simple text file wrapped at 80 columns, for those who may wish to print out a copy and tuck it into the back cover or something.
I also link to the code samples, in both gzipped-tar and ZIP formats. Throw in a nice spicing of web service-related links, links to reviews, and that's about enough for the page I figure.
Again, the page is here.
