htmldog: http://htmldog.com/ is good resource. i know this is a far stretch but they're some really good books out there for quick referencing...i know it's not as fast as opening a new tab, but some of the books: "the definitive guides" are great.
"Tizag, which is second in the results, is a pretty good resource."
Their Perl tutorial set is pretty terrible. They call it "PERL" (it's Perl), they believe the latest stable version is 5.10 (it's 5.14) and the code samples are simply awful.
