7. Harry Potter Saga
Total sales: (more than) 500 million copies
Harry Potter books are sold in more than 500 million copies worldwide and translated into 80 languages. It’s also one of the best selling products in USA. Even though the first copy was published by Bloomsbury in 1997, today you can find both in print and eBook versions of all seven books. This leads to the fact that, approximately though, one in fifteen people around the globe owns at least one Harry Potter book. The best-selling book of the all seven is Harry Potter and the Philosopher’s Stone, but the place for the fastest selling book of fiction of all time is reserved for Harry Potter and the Deathly Hallows, the final book in the series. Although the story about the adventures of young wizard Harry and his friends did finish in this final book, the Harry Potter books’ editions are moderately evolving throughout the brand-new, state-of-the-art cover illustrations which make these books seem even more ‘collectible’.
