There are some books around like Oreillys, i like to lay a book beside my laptop i find it more useful than switching to the browser or arranging windows when programming and reading ressources ... "CGI Programming with Perl" (i found only a edition from 2001, maybe this is the latest? If you choose the course mentioned there you get the book with the course, but i have only read very view so i cannot comment on this right now ...
/Spoiler oreilly course:
If you like to spend some money, maybe this would be nice:
(I enrolled to it, but i only started a few lessons, cause i subscribed to other courses too. And cant say if it is really "worth" the money, but the explanations are good, and the practice lessons are well designed, you get a personal instructor (which seems to have a good knowledge and answered all my questions so far ...) in Euro-Zone it is not that expensive anymore, maybe wait for a 15% cheaper they do this regularly)
