Would it be possible to build a plug-in to integrate Calibre with LibraryThing? It would be best to wait for the redesign to finish up as they're revamping the add books function as part of it, but what I was envisaging was a plug-in to use calibre metadata to fill in the manual entry form.
Most books are added via a title / author / isbn / publisher / asin search from various data sources, but every so often you have to do a manual entry (especially for pre-ISBN titles.)
