"Hyperlink author names to author profile page" does not work without also checking "Hyperlink author names"

That patch shouldn't be required at all since the functionality was incorporated into the module years ago.

What exactly is the problem you are having?

Try this module without enabling links to nodes:

https://www.drupal.org/project/biblio_author_node

I think the problem is located on biblio_handler_field_contributor class of Biblio module (I have customized this class on my module).

This conditionally requires both author link settings, which was what I was hoping to avoid.

Simple solution, override the theming function to allow the author profile links but not biblio author filter links. My initial modified version that accomplishes this, see theme_biblio_author_link() for the full code.

  $author = $variables['author'];
  if (variable_get('biblio_author_link_profile', 0) && isset($author['drupal_uid'])  &&  $author['drupal_uid'] > 0) {
    $base  = variable_get('biblio_base', 'biblio');
    $options = isset($variables['options']) ? $variables['options'] : array();

    $uri = drupal_parse_url(request_uri());
    $uri = array_merge($uri, $options);
    if (!isset($uri['attributes'])) {
      $uri['attributes'] = array('rel' => 'nofollow');
    }
    $path = $uri['path'];
    if (variable_get('biblio_links_target_new_window', null)){
      $uri['attributes'] +=  array('target'=>'_blank');
      $uri['html'] = TRUE;
    }
    $uri['attributes'] += array('class' => array('biblio-local-author'));
    $alias = drupal_get_path_alias($path);
    $path_profile = variable_get('biblio_show_profile', '0') ? "$path/$base" : $alias;
    return l(trim($author['name']), $path_profile, $uri);
  }
  else {
    return check_plain(trim($author['name']));
  }

Check that both settings are checked for this to work and the caches are flushed :)

Flagging fixed, reopen if I was completely off track (I'm not the maintainer).
