Well, "Intermediate Perl" is not one of my favourites sadly merlyn, I am glad you didn't mention "Learning Perl Objects, References and Modules"! Whilst I like your columns I have found that one in particular difficult to follow. However, "Learning Perl" is never far away, it is on the shelf right behind me.

I taught myself OOPerl from "learning Perl Objects" but didn't understand it and become comfortable with it until "Object Oriented Perl", I am also a fan of "Perl Best Practices" ( thedamian ) and "Higher Order Perl" ( dominus ).

But why does nobody mention "Effective Perl Programming" (Hall and Schwarz 1998), it is still a handy reference with some good ideas, and the 20 pages on Object Oriented Programming forms a conconcise introduction to the topic.
