L. A. Bosman

The provided text discusses the challenges in accurately determining the sales figures of authors, particularly those with extensive bibliographies spanning various languages. It outlines a list of best-selling fiction authors, based on approximate sales numbers from reliable sources, with a threshold of at least 100 million copies sold. The text clarifies that authors of comic books are generally excluded unless their work has been published in book formats like graphic novels or collected editions. It also notes that certain highly prolific authors, such as Jane Austen, Charles Dickens, and Jules Verne, are not included in the main list due to the unavailability of exact sales data, despite the possibility that their total sales might exceed the 100 million mark. The source material focuses on the methodology and limitations of compiling such a sales list, rather than providing detailed biographical information about individual authors like L. A. Bosman.
