Advanced Perl Programming
Object Oriented Perl
Perl Cookbook
Learning Perl
Programming Perl (1,2)
Programming the Perl DBI
Mastering Algorithms with Perl
The Coriolis Black Book
Perl 5 by Example (Que)
and while its not really a perl book per se,
Mastering Regular Expressions

Of all of them, first, the O'Reilly books really stand out. Theyre written at a level one would expect from the subject matter. Theyre written by knowledgeable authors in a very engaging tone, with few typos and many enjoyable examples.

The Coriolis book is, well, its kind of like a dictionary. You keep it around because its a good reference... but you dont ever actually sit down and read it.

The Que book is plain drek. I wouldnt even use it to mop up oil stains in my garage.

I suppose my favorites are Conway's book, OO Perl, or MAWP. There is just such a tremendous amount of material in both of them that I find I can come back to them with every project I undertake and not only learn something new but totally enjoy reading the book (Again!).

In the past I've really enjoyed reading the DBI book ... the subject matter is very light due to the fact that the perl DBI is so easy to work with, and the book is pretty thin. Sometimes you just want to sit down and soak your brain in some mild perl however, rather than really getting into the meat-n-potatoes of stuff.

Advanced Perl Programming, as well, is a fantastic book. Certainly well above beginner level however, and I find that I need to take a breather every few pages, go back, and cogitate on what it is I am proposing to learn (or study).
