Hmm... Perl books that I own...

• Programming Perl (2nd & 3rd ed)
• Learning Perl (1st & 2nd ed)
• Advanced Perl Programming
• Mastering Algorithms with Perl
• Perl in a Nutshell
• Effective Perl Programming
• Perl: The Programmers Companion
• Perl 5 Descktop Reference (all 3 eds)
• Object Oriented Perl
• Elements of Programming with Perl
• CGI Programming with Perl (1st & 2nd ed)
• Perl Reference Kit (Unix version)
• The Perl Cookbook
• Graphics Programming with GNU Software and Perl
• The Official Guide to Programing wih CGI.pm
• Learning Perl/Tk
• Perl/Tk Pocket Reference

and probably a few more that I've forgotten.

As for how good Object Oriented Perl is, in my opinion it is the best-written and most useful book in my whole collection.
