I have yet to live up to my promise and write a review of Modern Perl (part of the problem is that I have a glut of books that I received over Christmas).

Perhaps you'd like to read David Golden's brief review?

Anyway, the book has always been available electronically and for zero cost. Available in multiple electronic formats. I have read much of the book and it is very good. I recommend anyone who is a Perl programmer to read it. Also recommended for programmers who aren't everyday Perl developers.
