Writing a best-selling novel is one thing; sustaining a legacy across decades—or even centuries—is another. The authors on this list have done just that, connecting with generations of readers through both sheer volume and lasting impact.
To qualify, prolific output plays a major role. The fewest books published by any author here is 23, while some exceeded 100—one by a staggering margin (Barbara Cartland holds the record with over 700 novels). However, popularity also matters. J.K. Rowling, with just 11 novels, is rapidly climbing the all-time Top 10 thanks to the enduring success of Harry Potter.
