The mark of a superb book on computing (and technology) is that is ages like a fine wine. There are a tremendous number of "old" Perl books that are still in effect worth their weight in dead trees. Best part is that you can scoop these books up very cheaply on your online book purveyor of choice.
Examples include:
- Computer Science & Perl Programming: Best of TPJ (Orwant)
- Network Programming with Perl (Stein)
- Extending and Embedding Perl (Jennes, Cozen)
- Perl for System Administration (Blank-Edelman)
- Perl Cookbook (Christiansen, et al.)
- Advanced Perl Programming (Cozens)
- Data Munging with Perl (Cross)
The trick is learning to ignore some of the old idioms or discouraged idioms that are present in the books. Things to avoid: Using old skool CGI for web applications and crusty versions of Perl and XML (Ray, McIntosh) - not sure of the freshness of later editions of the latter, but earlier editions recommend some modules that are not longer encouraged. But it also doesn't really demonstrate some foundational uses of Perl either like the others I've recommended.
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
Read Where should I post X? if you're not absolutely sure you're posting in the right place.
