Then I tried to import my list of books from Goodreads, and the result was abysmal: fields are selected and applied at random, and I had to remove the db since it was useless. Even if Alfa did not know the semantics of the fields used by Goodreads, I would have expected that the software would have presented me a sample line, asking to put the fields in the correct position…
