Demo for Google Book Classes

Google Book Classes wraps the Google Book Viewability API in a set of easy-to-use HTML widgets to merge information from Google Books into a webpage. Use "View Source" to examine the simple HTML tags that have created the content you see below.

The Google Book Classes (gbs) are available under the LGPL license. If you deploy it, please host gbsclasses.js on your own machine.

For users of the III Millennium OPAC, these slides describe how to integrate GBS into your OPAC.

Examples: 

<span title="ISBN:0061234001" class="gbs-thumbnail"></span>

<span title="ISBN:0596000278" class="gbs-thumbnail gbs-link-to-preview"></span>

<span style="display:none" title="ISBN:0596000278" 
   class="gbs-link-to-info gbs-if-partial gbs-remove-on-failure">
  <img src="http://code.google.com/apis/books/images/api-example2.png">

Note: Google appears to have a relatively large numbers of ISBNs misindexed. I am suspecting that in general, OCLC# or LCCN# may be better identifiers to use.

Example 1: ISBN:1402038682 (misindexed)   OCLC:63180607 (correct)   LCCN:2006436815 (correct)  

Example 2: ISBN:1402030533 (misindexed)   OCLC:60679740(correct)   LCCN:2005275561 (correct)
