I have to agree with the earlier poster, who said most everything can be found in perldoc (and 'man perl***').
I have an early copy of the camel, but I _never_ use it. The main reason is that I feel the text rambles. I must admit reading it is entertaining, but barely what I would want to use as a reference.
Also, why use a printed book as a reference when the electronic documentation is updated along with the perl version? The book is destined to become hopelessly out of date, while perldoc/man perl*** is almost always current.
Your money is better spent elsewhere.
