I own quit a lot of books on Perl. But when I look on
my desk or bookshelfs the only ones you don't want to
touch without rubber gloves are Mastering Regular
Expressions and Camel 2. Look at this books and
you will know they had a hard time and traveled a lot.
in reply to Mastering Regular Expressions
If you are not one of the "Wash your hands before you
thouch the book" & "Allways treat books nicely"
pedants you will know which are your most valuable books
just by looking at them.
In my opinion this book is one of the most exciting, helpfull
and entertaining computer books I have ever bought. And it is
not difficult, but easy to understand. Just 2 weeks
ago I gave it to a linguist colleage (without programming
experience) of mine and even she got excited on Regular Expressions
while just using different dialects of grep.
Its not just a Perl book, but The Survival Guide for
people with too much Data.
