Wait... Although this is a good book, it doesn't mean that it'll teach you perl. It actually doesn't intend to teach you perl from basics. What I really love about this book is, it gives a reader lots of ideas on how to use perl efficiently.
Those who are hoocked on CGI can also buy this book. After buying the book you can either 1)read through it and have new ideas on how you could write perl programs efficiently or 2) just grab the ready-to-use programs from the CD and run'em. I agree, this is not the only book that provides you with ready-to-use programs. I also wrote a review to CGI/Perl Cookbook, which got my just one star. Difference between these two titles is that, CGI/Perl Cookbook is pretty far from giving you tips and doesn't go through their ready-to-use programs in details. As to Perl:Annotated Archives, it does a good job on explaining the programs. Also the programs included in the book are intended to handle some very frequent tasks, like checking HTML validity, Managing your news pages, CGI security (for details look at the table of contents in the left menu).
If you are beginner and want to learn perl and to be able to write your own programs and modules, I do not recommend you this title. Don't buy it. Go for either CGI101(highly recommend it) or Elizabeth Castro's Quick Start guide.
In overall, this is a good book, which provides you with lots of usefull ideas and programs as well.
