Larry Wall originally created Perl while a programmer at Unisys. He now works full time guiding the future development of the language as a researcher and developer at O'Reilly & Associates. Larry is known for his idiosyncratic and thought-provoking approach to programming, as well as for his groundbreaking contributions to the culture of free software programming. He is the principal author of the bestselling Programming Perl, known colloquially as "the Camel book."
Tom Christiansen is a freelance consultant specializing in Perl training and writing. After working for several years for TSR Hobbies (of Dungeons and Dragons fame), he set off for college where he spent a year in Spain and five in America, dabbling in music, linguistics, programming, and some half-dozen different spoken languages. Tom finally escaped UW-Madison with B.A.s in Spanish and computer science and an M.S. in computer science. He then spent five years at Convex as a jack-of-all-trades working on everything from system administration to utility and kernel development, with customer support and training thrown in for good measure. Tom also served two terms on the USENIX Association Board of directors. With over fifteen years' experience in UNIX system administration and programming, Tom presents seminars internationally. Living in the foothills above Boulder, Colorado, surrounded by mule deer, skunks, and the occasional mountain lion and black bear, Tom takes summers off for hiking, hacking, birding, music making, and gaming.
Jon Orwant, a well-known member of the Perl community, founded The Perl Journal and co-authored OReillys bestseller, Programming Perl, 3rd Edition.

it gave TOO much info on many subjects and verged into being a
tutorial rather than a reference and often did not quite succeed at
being either. It's neither fish nor fowl.
Why 100+ pages on regular expressions given the excellence and
thoroughness of Friedl's book "Mastering Regular Expressions"?
Why data structures section given that this strays into the Cookbook's
domain but doesn't really go quite far enough to be a complete tutorial.
Other very, very important topics where the O'Reilly books are way, way
out of date (like the DBI book) aren't made up for by the Camel book.
Indeed, databases are scarcely mentioned much less covered. The
book also falls short by virtually not mentioning crucial directory-related
operations like recursive descent with FIle::Find. This subject is of vital
interest to sysadmins and QAs using Perl to make product build scripts
where movement around directories is at a premium.
This Camel is okay but, alas, like so many latter-day O'Reilly products,
it just doesn't measure up to its predecessors.
I'm a professional Programmer and I already master other Programming Languages, but I am completely new at Perl. So I could reference many concepts from other Programming Languages.
The book gave me the basic concepts of Perl that I needed to get started with Perl and get very soon the Results I need for my Job in 2 Projects.
But I saw that the Book holds even more to study more in depth details about Perl to achieve higher Performance of the Scripts as for example details of the Compiling Process that could be useful to get more processing speed, or details about the Garbage Collector that could help to save Machine Resources.
I will certainly still come back to this Book for more in depth study to attain more mastery over this powerful Programming Language Perl.
Don't get me wrong. I love using Perl, and this book is very interesting at times because Larry Wall is an interesting guy. But the discussion is a little dithering and philosophical.
It also has very few example programs. The book recommends that you use _Perl Cookbook_ (from the same publisher) as a companion. While _Perl Cookbook_ is a very good book, it's kind of silly to buy two books if you just want to learn intermediate Perl concepts.
As an alternative to _Programming Perl_, I highly recommend _Intermediate Perl_ from the same publisher (it has an alpaca on the cover). _Intermediate Perl_ is more concise; more informative; better structured; and has more examples.
If you are a casual programmer though, I must caution you that this book is pretty intense reading. I found it helps to read this book while reading the "Perl Cookbook". The chapters for each book correlate to each other. This book explains how everything works, while the Cookbook shows you how to apply these concepts in real life situations.
One complaint I had about this book were the unclear examples. Other books by O'Reilly such as "Learning Perl" and "Perl Cookbook" will label each line of code in their examples so that there is no ambiguity. However the example scripts in this book are sparsely labled, so it is not always clear what the author's intent is.
However, if you feel up to the challenge, I would definitely recommend this book. After reading this book, your understanding of Perl will improve dramatically. In addition, the last few chapters will provide a very useful reference regarding Perl's many modules, functions and such. For serious programmers, you will thank yourself for buying this book.
