How to Display a List of Blogs (Blog Titles only)

I am attempting to modify Kitt's excellent tutorial on creating modules to accomplish this. So far, I have been able to create a custom block that will list blog nodes using the following code:

function bloglist_block($op='list', $delta=0) { 

  // listing of blocks, such as on the admin/system/block page 
  if ($op == "list") { 
    $block[0]["info"] = t("Blog List"); 
    return $block; 
  } else { 
  // our block content 

    // content variable that will be returned for display 
    $block_content = ''; 

    // Get list of blogs 
    $query = "SELECT nid, title, created FROM " . 
             "{node} WHERE type = 'blog'"; 

    // get the links 
    $queryResult =  db_query($query); 
    while ($links = db_fetch_object($queryResult)) { 
      $block_content .= '< a href="'.url('node/view/'.$links->nid).'" >'. 
                        $links->title . '< /a>< br />'; 
    } 
	
    // set up the block 
    $block['subject'] = 'Blog List'; 
    $block['content'] = $block_content; 
    return $block; 
  } 
}

This is going in the direction that I would like, but it is not there yet: I want the block to list just the Blog Titles (i.e., the Parents of each blog node --not the titles of the nodes (i.e., blog entries) themselves.

Unfortunately, I am a PHP/Drupal newbie and don't know where to turn. Any guidance/pointers in the right direction is appreciated. Thx,

Donovan.
