worksvenn.py is a tool to analyze the coverage of the OpenLibrary, OCLC and LibraryThing FRBRization services. If you give worksvenn.py an ISBN it will talk to the three APIs to get all the related edition ISBNs, and then compare the results by printing out which ISBNs are unique to each service, and a Google Chart URL for a Venn diagram visualization of the results. Here's what the chart looks like for William Gibson's Neuromancer (ISBN 0441569595)
To generate this image you just call worksvenn.py:
% ./worksvenn.py 0441569595
And you will see the following output:
