Subject: SRU - can I do a lookup via ISBN?
I am an utter newbie to SRU and would be very grateful for your help.
I am trying to implement an application in which the user
(a) first scans an ISBN from a book, then
(b) does a lookup via SRU to get information from the Library of Congress (and thereby avoid manual entry).
I am using (for example)
and I am getting back:
diagnostic: message: Unsupported index
However, if I get the Explain record, it says
So I would have thought that what I attempted to do was legal.
 What am I missing here?
 How can I do an ISBN lookup?
Thank you for your help.
