The 10 most popular books often feature high sales and cultural impact, with classics like Don Quixote, A Tale of Two Cities, and The Little Prince topping lists, alongside modern phenomena like Harry Potter and The Lord of the Rings, showing a mix of religious texts (Bible, Quran), fantasy epics, classic literature, and children's stories dominating global readership.
According to Wikipedia, there are nine books that have sold more than 100 million copies.
