Rankings
Our rankings of the greatest books are derived from a variety of credible lists, each given a weight based on its quality and influence.
We start with an ideal 'weight' of 150 for a perfect list. This weight can be reduced based on factors like the list's credibility and its alignment with other reputable lists. Weights can go as low as 1 for lists with minimal influence.
Books that appear on multiple lists gain more points due to their consensus value. However, we also give credit to books that make it to a single high-quality list, ensuring a balanced and fair ranking.
