There's nothing wrong with escaping quotes, but Perl has enough quote
notations that it is almost never a "have to" to escape them. You could
define your variables like this:
my $bilbo = qq{Bilbo,"Why I like rings" Freemont Press, 1998,};
my $frodo = qq{Frodo, "Why I don't" Bridgedale Freemans, 183};
That will incorporate the double quotes into your variable without having to
escape them. That can just make them easier to read since there is no escape
character to confuse when reading.
Again, nothing wrong with what you did, I just wanted to point out that
escaping was not a "Have to".

"Hello out there - I have learned a lot of Perl today, but I am still

to figure one more thing out.
How can I go through a file and extract all the text between certain
delimiters - for example I have:
Bilbo, "Why I like rings" Freemont Press, 1998.
Frodo, "Why I don't" Bridgedale Freemans, 1832
Etc
I want to get:
Why I like rings
Why I don't
It seems like there should be a real quick way to do this. . . thoughts?

You could look at the page and see what the phrases have in common, then
make a regex delimiter to extract them. see below:
#!/usr/bin/perl -w
use strict;
my $bilbo = "Bilbo,\"Why I like rings\" Freemont Press, 1998,";
my $frodo = "Frodo, \"Why I don't\" Bridgedale Freemans, 183";
my @array=($bilbo,$frodo);
#I want to get:
#Why I like rings
#Why I don't
foreach(@array){
(/(".*")/) ? print $1 . "\n" : print "not your string\n";
}
In the above example i had to escape the quotes to use them. If you have
a whole plain text file of you can just use the open(FILE, "myHobit") ||
die "$!"; then use a similar search. Have fun.
