Hide Field Publication Type in Node View

The short answer is no, not directly like other fields.

The longer answer is... if you wanted to override the theme_biblio_tabular($variables) theme function you could, since the Publication type and Title are more or less hard coded into that theme function.

Here is how I used the theme override (thought it may help others.)
Note: I'm using the Tabular View
I added this to my template.php (copied from the module biblio/includes/biblio_theme.inc), and modified
- commented out two fields that are build in (see /***)
- added an elseif to skip any fields that I didnt want displayed (see //***)

/**
 * @param $node
 * @param $base
 * @param $teaser
 * @return unknown_type
 */
function responsive_biblio_tabular($variables) {
  module_load_include('inc', 'biblio', '/includes/biblio.contributors');
  $node = $variables['node'];
  $base = $variables['base'];
  static $citeproc;

  if (module_exists('popups')) {
     popups_add_popups();
  }
  $tid = $node->biblio_type;
  $fields = _biblio_get_field_information($node->biblio_type, TRUE);
  
/*** - commented out so this field wont show on biblio nodes  
  $rows[] = array(
    array('data' => t('Title'), 'class' => array('biblio-row-title')),
    array('data' => filter_xss($node->title, biblio_get_allowed_tags()))
  );
*/
  if (!isset($node->biblio_type_name) && isset($node->biblio_type)) { // needed for preview
    if (($pub_type = db_query('SELECT t.tid, t.name FROM {biblio_types} as t WHERE t.tid=:tid', array(':tid' => $node->biblio_type))->fetchObject())) {
      $node->biblio_type_name = drupal_ucfirst(_biblio_localize_type($pub_type->tid, $pub_type->name));
    }
  }
/*** - commented out so this field wont show on biblio nodes
  $rows[] = array(
    array('data' => t('Publication Type'), 'class' => array('biblio-row-title')),
    array('data' => $node->biblio_type_name)
  );
*/

  $attrib = (variable_get('biblio_links_target_new_window', FALSE)) ? array('target' => '_blank') : array();

  $doi = '';
  if (!empty($node->biblio_doi)) {
    $doi_url = '';
    if ( ($doi_start = strpos($node->biblio_doi, '10.')) !== FALSE) {
      $doi = substr($node->biblio_doi, $doi_start);
      $doi_url .= 'http://dx.doi.org/' . $doi;
      $doi = l($doi, $doi_url, $attrib);
