First off a HUGE Thank you to the author as this is one of my favorite sites to get book information.
I also had a question/request I hope is possible.
Is there any chance you could adapt this script to work with MP3Tag as a source to help tag audiobooks?
MP3Tag is one of the better free tagging software I've found and the fact you can create your own sources to pull data from makes it the best in my opinion.
I've attached two Mp3Tag sources that work with pulling tags from audible and discogs as a reference if you would be so good as to take a look.
