Although biography and other types of books were both dropped 5 percent from their initial percentage, the shares of travel books and children’s fiction ascended 2 or 3 percent, respectively. Adult fiction, however, indicated the highest percentage of 25% as opposed to the stated books.
Coming to the year of 2012, purchasing of books underwent rapid changes typically.
