=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.

=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.
