Hyphens were added to all the ISBN numbers to make the format more consistent.
Also updated and included the ISBN13 on all book info cards.
On the sorted page with ISBN numbers the books are now sorted by the country where the book was published.
Note that books with no ISBN and books with an (at the moment) unknown ISBN are not sorted by country.
For most of the books, however, the country is shown on the book info card.
