=head1 NAME
Net::Amazon::Property::Book - Class for books on amazon.com
=head1 SYNOPSIS
  use Net::Amazon;
  # ...
  if($resp->is_success()) {
      for my $prop ($resp->properties) {
          print join("/", $prop->authors()), " ",
                $prop->title(), " ",
                $prop->publisher(), " ",
                $prop->year(), "\n";
  }
=head1 DESCRIPTION
C<Net::Amazon::Property::Book> is derived from 
C<Net::Amazon::Property> and on top of the all-purpose
methods the base class provides, it offers specialized accessors for
book parameters.
=head2 METHODS
=over 4
=item authors()
Returns a list of the book's authors. There's also a C<author()> method
which just returns the I<first> author.
=item publisher()
Returns the book's publishing company as a string.
=item title()
Returns the book's title as a string.
=item isbn()
Returns the book's ISBN number.
=item edition()
Returns the book's edition.
=item ean()
Returns the book's EAN number.
=item numpages()
Returns the number of pages.
=item dewey_decimal()
Returns the Dewey decimal number, this is for non-fiction only.
This method is deprecated (2011-10-28) as it does not appear to be returned by
Amazon any more.
=item publication_date()
Returns the publication date.
=item ReleaseDate()
Returns the release date.
For historical reasons, this method used to return the publication date. 
However, as of version Net::Amazon 0.44 the release date is returned, and 
a separate L</publication_date()> method is available. 
=item new(xmlref => $xmlref)
Initializes an object by passing a hash of hashes structure containing
the XML data returned from the service. Usually, this is just used by
C<Net::Amazon> internally to initialize objects for on backcoming
data.
=back
Check out L<Net::Amazon::Property> for all-purpose accessors, like
C<year>, C<OurPrice>, C<ListPrice>, etc.
