Export link to Worldcat

Hi Ron,

In Biblio one has the possibility to activate export links to e.g. Google Scholar and PubMed. Can you do the same for an export link to Worldcat? I changed/added a little to your code and made it work, but as am I not a PHP programmer it is probably not the correct way of doing! Besides it would be better not to jingle with your code...

Here are the lines i added:

file biblio.module
line 449: $show_link = variable_get('biblio_export_links', array('tagged' => TRUE, 'xml' => TRUE, 'bibtex' => TRUE, 'worldcat' => TRUE));
line 455: if ($show_link['worldcat']) $links['biblio_worldcat'] = _build_worldcat_link($node);

file biblio.admin.inc
line 331: '#default_value' => variable_get('biblio_export_links', array('rtf', 'tagged', 'xml', 'bibtex', 'worldcat')),
line 337: 'worldcat' => t('Worldcat'),

file biblio_theme.inc
line 875: $show_link = variable_get('biblio_export_links', array('rtf' => TRUE, 'tagged' => TRUE, 'xml' => TRUE, 'bibtex' => TRUE, 'worldcat' => TRUE));
line 885: if ($show_link['worldcat'] && !empty($node))
line 886: $links .= '

';
line 923: case 'worldcat':
line 924: $link = _build_worldcat_link($node);
line 925: break;
line 1038-1049:
function _build_worldcat_link($node) {
$query = array();

$query['q'] = '"'.str_replace(' ', ' ', $node->title).'"'; // q = all the words

return array(
'title' => t('Worldcat'),
'href' => 'http://www.worldcat.org/search',
'attributes' => array('title' => t("Click to search Worldcat for this entry")),
'query' => $query,
);
}

Hopes this gives you a hint of what I mean.

Thanx and best regards, Christian.
