I'd like to humbly announce that I've written a pre-pre-alpha Python
module for working with the WorldCat Search API and the xID APIs. The
code needs a fair amount of work, namely unit tests and documentation.
I've released the code under the GPL.

The module, called "worldcat," is available from the Python Package
Index at <http://pypi.python.org/pypi/worldcat/>. You can also
checkout a copy of the code from my Subversion repository at
<http://svn.matienzo.org/public/python/worldcat/>.
