Goodreads used to have an API but they stopped giving access and it looks like they are shutting it down. A real garbage move.
I like to be able to use my data that I put in so I wrote a script to automatically download my data regularly. Then I can do stuff like check to see if books I want are in the library or keep my own list or analytics, etc.
Hereâ€™s the python script to export your good reads library, hope it helps you. Iâ€™ll put it in the public domain.
