Add google books links

Something like the code in Tim Spalding's Thingology Blog.

<div id="gbsthumbnail"></div>
<div id="gbslink"></div>

<script type="text/javascript">

/* GBS Cover Script by Tim Spalding/LibraryThing */

function addTheCover(booksInfo)
{
var gbsnameA = new Array("No information", "Book info", "Partial view", "Full view");

for (i in booksInfo)
 {
 var book = booksInfo[i];
 
 var quality = 0;
 if(book.preview == "noview") { quality = 1; }
 if(book.preview == "partial") { quality = 2; }
 if(book.preview == "full")  { quality = 3; }
 
 if (book.thumbnail_url != undefined)
  {
  document.getElementById('gbsthumbnail').innerHTML =
   '<img src="' + book.thumbnail_url + '">';
  }
 if (quality > 3)
  {
  document.getElementById('gbslink').innerHTML =
   "<a href=\'" + book.preview_url + "\'>" + "Google Books: " + gbsnameA[quality] + "</a>";
  }
 }
}
