Okay, I felt guilty for giving this such a terse answer, which wasn't very helpful (IMHO). So here's a list of places I'd look for Perl info (by no means complete)--
At your fingertips on any machine with Perl installed: perldoc: type in perldoc perl and behold the wonder. Modules: core modules are already on your machine. Some of them are written in Perl. No one is going to stop you from looking at the source to these, just open your favorite *.pm file in emacs (or whatever editor you may have on hand) and see what it looks like when the masters write Perl. Just don't save any changes. :)
web-based stuff (largely repeats from Outside Links)
The O'Reilly Perl Center: Good books about Perl. Home of the Camel and other Frequently Essential Perl Books. The Perl Journal: magazine about Perl, has some stuff online (subscribers get full archive access!)
