Rating:  - Best...Perl book.... ever
Most O'Reilly Perl titles imply you'll learn something useful. Only Learning Perl and the Perl Cookbook fully come through in that regard.
The Perl Cookbook features some very practical solutions to some very practical problems (in Perl).
I find myself coming back to this one again and again - more so than Learning Perl, Programming Perl, Programming the Perl DBI, or Perl Best Practices. This is The One. The book to use to learn the Right Way to perform quite a large number of useful functions or tasks in Perl.

yummy perl recipes; easy to prepare! very helpful for working with date and time data.
Rating: - Non Fiction
Very useful, well worth it. Getting a book like this and having it save you the time of working out how the (yes, come on, admit it, a lot of perl syntax etc. is quite arcane) actual program should be set out, formatted or whatever, is fantastic. Several times this book has done that for me, so one of the best computer book purchases I have ever made.

Once you've learnt the syntax of a language, you want to learn the idioms, and how it's used most effectively. And given Perl's famous 'There's More The One Way To Do It' motto, you'll need all the help you can get. Perl Cookbook is that help.
Neither a reference nor a tutorial, if you've ever read another cookbook, you'll know what to expect -- after all, this is the daddy of them all. Themed chapters, consisting of short tasks that most people will find handy e.g. trimming white space from a string, or populating a hash. What makes Perl Cookbook so valuable is not just finding out how to do it, but finding out what the most efficient and idiomatic way to do it is. This is where you'll see the Perl way of doing things in action, and it's an immensely valuable learning experience, even if you never need to do exactly any of the things in the book.
For me, the most vital material is the earliest stuff, which takes you through how to use the string, array and hash, the guts of any Perl program. The final half of the book explores Perl's libraries for the use of databases, and a lot of network and web-related stuff, from simple socket programming, to CGI, and the use of mod_perl.
This is a cornucopia of Perl lore, firmly established in the Perl Canon, and deservedly so. You want it on your bookshelf if you want to really call yourself a Perl programmer.
Rating:  - Code examples that you can use and learn from
As a programming cookbook, this book presents a bunch of problems that you, as a Perl programmer, may encounter in your everyday development work and then shows you both the code that solves the problem and a lengthy discussion on how the code works. So far none of the problems has applied to my everyday Perl development chores, but by simly reading through some of the more interesting problems, I've learned a great deal more about Perl than before.
So this book works well as a learning tool for someone who already knows Perl but is still intrigued by its vast arsenal of powerful features -- and arcane usage. Any serious Perl programmer can be helped by this book, whether he or she finds the examples in the book directly applicable or not.
