Field Formatter, Display Formatted Biblio CCK Nodereferences

Hi, just thought I would post this snippet of code for formatting CCK Node References as Biblio references. I am new to Drupal and really needed this feature to add a way for my users to select publications to display on their staff pages. If the node types aren't biblio ones it just defaults to creating a title link. I currently have this code in my own module but I think it would be good to see it added to Biblio for others to use.

/**
 * Implementation of hook_field_formatter_info().
 */
function biblio_field_formatter_info() {
    return array(
        'biblio' => array(
            'label' => 'Biblio (reference)',
            'field types' => array('nodereference'),
        ),
    );
}

/**
 * Implementation of hook_field_formatter().
 */
function biblio_field_formatter($field, $item, $formatter, $node) {
    if (!isset($item['nid'])) {  
        return '';  
    }
    switch ($formatter) {
        case 'biblio':
            $full_node = node_load($item['nid']);
            if ($full_node->type == 'biblio') {
                return theme_biblio_list($full_node);
            }
            //If not a biblio node just output a title link.
            else {
                return l($full_node->title, 'node/'. $item['nid']);
            }
        break;
    }
}
