I have been trying to figure out hash of hashes. I have found a few URLs, but the examples aren't clicking. Here is the code I am playing with and output.

use Net::Amazon;

my $ua = Net::Amazon->new(token => 'xxxxxxxxxxxxxxxxxxxx', locale => '
+us');
my $response = $ua->search(browsenode=>"3839", mode=>"books", keywords
+=>"perl");

if ($response->is_success()) {
     for my $prop ($response->properties) {
          $books{$prop->publication_date()}{'title'}        = $prop->t
+itle();
      $books{$prop->publication_date()}{'authors'}      = join(", ",$p
+rop->authors());
      $books{$prop->publication_date()}{'isbn'}         = $prop->isbn(
+);
      $books{$prop->publication_date()}{'pages'}        = $prop->numpa
+ges();
      $books{$prop->publication_date()}{'publisher'}    = $prop->publi
+sher();
      $books{$prop->publication_date()}{'image_small'}  = $prop->Image
+UrlSmall();
      $books{$prop->publication_date()}{'image_medium'} = $prop->Image
+UrlMedium();
     }    
     print Dumper %books;
}

Data Dumper outputs 
$VAR1 = '2005-07-12';
$VAR2 = {
          'image_medium' => 'http://ecx.images-amazon.com/images/I/21m
+kODqYmdL.jpg',
          'authors' => 'Damian Conway',
          'title' => 'Perl Best Practices',
          'isbn' => '0596001738',
          'publisher' => 'O\'Reilly Media, Inc.',
          'image_small' => 'http://ecx.images-amazon.com/images/I/11Ol
+nA6slCL.jpg',
          'pages' => '542'
        };

I expected $VAR2's content to be under $VAR1? On a side note, does anyone know why there is a "\" in "O'Reilly" in the publisher key?
