in reply to Understanding how to *use* a CPAN module

The documentation for this set of modules is a bit spread out, but you're on the right track. Your $result is an iterator object because you did a search. If you want a single book record for a specific isbn, use the example from WebService::ISBNDB::API::Books: 
my $book = WebService::ISBNDB::API->new({ api_key => $key,
                                          isbn => '0596002068' });
my $title = $book->get_title();

The code you need is all in the docs.

    perrin,

    I had tried that and was getting zero results (white screen). When I moved the api_key up to the use declaration, I started working. Must be a bug.

    #!/usr/bin/perl

use strict;
use CGI::Carp qw(fatalsToBrowser);
use Data::Dumper;
                                 
use WebService::ISBNDB::API (api_key => '12341234');
use WebService::ISBNDB::API::Books;

my $book = WebService::ISBNDB::API::Books->new('0596002068');

my $title = $book->get_title();
my $authors = $book->get_authors_text();

print "Content-type: text/plain\n\n";
print Dumper($title, $authors);

1;

    Returned:

    $VAR1 = 'Programming Web services with Perl';
$VAR2 = 'Randy J. Ray and Pavel Kulchenko';

    It really helped to look at the tests. Then the docs made more sense.
