Perl Recommended Reads

[stryda42]

Hello Perl Monks

I have been using perl for a few years now and I really (really) enjoy the language.
And I want to know more about the language.

So I have a few books here like:

Learning Perl
Intermediate Perl
Object Oriented Perl (just started reading this)

I'm sure there are other books that you know are worth reading.

So in an ordered list (1..5+), what Perl books have you read, that are worth reading?

What books do you feel, helped enhance your knowledge/career, etc in Perl?

I'd really appreciate this coming from you guys.
And my apologies if someone has asked this question, in the past.

Thanks!
