This document outlines a compilation of fiction authors whose book sales are estimated to have surpassed 100 million copies worldwide. The selection process relies on approximate sales figures gathered from reliable sources, acknowledging the difficulty in obtaining exact sales numbers for any author.

The list is specifically curated to include authors with a minimum estimated sales threshold of 100 million copies of their fictional works, whether written individually or collaboratively. Authors of comic books are only considered if their work has been published in a book format, such as graphic novels or collected editions. It is important to note that certain highly influential authors, like Jane Austen, Charles Dickens, and Jules Verne, are not explicitly included in the main table due to the absence of precise sales data, despite the strong possibility that their cumulative sales also exceed the 100 million mark.

The estimates presented are drawn from various years, meaning they are not directly comparable for precise ranking. The document also references related lists, such as best-selling books and novels within the United States, as well as best-selling manga, providing broader context to the landscape of popular literature.
