Some of the chapters are surprisingly short, and there are some typos, but nothing heart-stopping that I found.

Covers approaches other than Perl, including JavaScript. Explains the interface of CGI.pm quite well, in only a chapter.

Nice section on HTTP status codes you might return from a CGI program.

I was really hoping for a section on native query parsing -- perhaps a nitty-gritty CGI document is needed (which I happen to be writing).

All in all, a nice read. I was waiting all day for that UPS truck. :)
