Classify Web Service Bug

We wanted to let the community know that a recent install introduced a bug in the Classify web service. Typically the web service allows developers to send in a search by ISBN. This parameter is currently broken in the web service.

So the following request will fail:

with a response of

<?xml version="1.0" encoding="UTF-8"?>
<classify xmlns="">
<!--Classify is a product of OCLC Online Computer Library Center:>
<input type="noParam">null</input>
<response code="100"/>

We will update you when we have a date for the fix to be installed. In the interim the Standard number index can also be used to search for an ISBN.


Please Contact Us if you have any questions.
