[link|http://www.perlmonks.org/|PerlMonks] IYF.

And some tips that I picked up from reading [link|http://www.perlmonks.org/index.pl?node_id=328435|this thread] which basically asks the same question...

Books: [link|http://www.bookpool.com/.x/m2n957kn0m/ss/1?qs=Learning+Perl&Go.x=0&Go.y=0&Go=Go|Learning Perl]; [link|http://www.bookpool.com/.x/m2n957sa6n/ss/1?qs=Programming+Perl&Go.x=0&Go.y=0&Go=Go|Programming Perl]; [link|http://www.bookpool.com/.x/m2n9571lz1/ss/1?qs=Perl+Objects&Go.x=0&Go.y=0&Go=Go|Learning Perl Objects, References, and Modules]; and [link|http://www.bookpool.com/.x/m2n957qzmi/ss/1?qs=Perl+Cookbook&Go.x=0&Go.y=0&Go=Go|Perl Cookbook].

There's also a node on PM that describes [link|http://www.perlmonks.org/index.pl?node=Where%20and%20how%20to%20start%20learning%20Perl|Where and how to start learning Perl]. I haven't reviewed it yet, but it at least has the appearances of being comprehensive.

Our very own [link|/forums/render/user?username=ben_tilly|ben_tilly] is one of the most revered PM members, and a [link|http://www.perlmonks.org/index.pl?node=Saints%20in%20our%20Book|Saint in Their Book], and I at least know a bit on the specific topics of CGI, DBI, and sessions (that tends to be what I've used Perl for in the past.)
