Dear hakiba,
Sorry for the delay in replying.
Yes, you are absolute right, you need open the book, change fetch source to amazon.com web service, click save & publish, this will fetch the info.
This process possible make faster, if we will take ISBN from file.
But you will need place all ISBN in one file.
It will be faster, but make process automatic not possible. Also, it will be customization service.
To get more details, please write on our contact form
