Please don't delete title when Not-a-Booking; don't change title to ISBN.

Please don't delete the title when Not-a-Booking. Especially don't change the title to the book's ISBN. (There's no need for that since the ISBN will remain in the record.)

According to the manual, you may optionally add NOT A BOOK to the beginning of the book's title, but this is not required.
