Hey Fudgel, I have looked into your CSV. It is working as I originally intended: it only displays books that are on your "to-read" bookshelves, as the idea is that you want to find a book that is not on your read list. You only have one book that is not on your read list.

Would you want/expect any other functionality? I assume you then mainly use GoodReads to keep track what you have read and not what you would like to read in the future?
