Since the Index counts translations of individual books, authors with many books with few translations can rank higher than authors with a few books with more translations. So, for example, while the Bible is the single most translated book in the world, it does not rank in the top ten of the index. The Index counts the Walt Disney Company, employing many writers, as a single writer.
The Index calculates book translations, leading to authors with fewer published works and more translations ranking higher than those with many books but fewer translations. For instance, although the Bible is the most translated book worldwide, it doesn't rank among the top ten in the index. The Index treats the Walt Disney Company, employing numerous writers, as a single author.
