The O'REILLY books are excellent IMO.
I have "Learning Perl" which provides a good intro to perl & is in a chatty style (very newbie friendly). It covers many of the core subjects, has snips of code & is easy to read cover-to-cover.
I also have "Programming Perl" which is coauthored by Larry Wall, the creator of Perl. Its also a great book & covers many of the topics in more detail.
Finally I have "Mastering Perl/Tk" for when I need a GUI for my scripts. It covers the basics of creating a frontend using Tk widgets & some of the general ideas befing good GUI design.
Anyway.. I would just like to take this opertunity to say I am really bad at perl but enjoy hacking stuff about & all 3 books have been usefull & interesting reads.
