I believe that selection is the reason why Danish book stores struggle. They try to present the same best sellers as the super markets, I assume because it's a safe bet.

At the same time I'm pretty much forced to buy from Amazon and buy books in English, because only the most popular books are translated, and primarily fiction. I don't get the impression that the bookstore really care to sell a larger selection of books, just more copies for the same 20 best sellers.
