We added a few more features in xISBN service recently:
- JSON callback
JSON output is native JavaScript, and callbacks are particularly useful for use with web service requests in client-side JavaScript. see:
http://xisbn.worldcat.org/xisbnadmin/doc/api.htm#callback
- tab-delimited format dissemination
This is useful if you need to do a unix cut:
$ curl "http://xisbn.worldcat.org/webservices/xid/isbn/0596002815?method=getEditions&fl=title,year&format=txt" | cut -f 2
