There are more than 100 works in the world competing for these two awards. The two American writers can share the prize of 70 thousand pounds.
Smith, a young British writer, won the prize of converting printed novels into e-books and won a prize of 7,000 pounds.
E-book awards are divided into four categories: original novels, non-fiction, printed novels into e-books and printed non-fiction into e-books.
The reason for holding this grand prize is to "affirm the importance and great potential of this new media to writers, publishers and readers all over the world".
