There are great books written, that were not popular at the time of publishing; but instead they became popular years and years later. Even worse, this data will be used by publishers as a filter what kind of books to produce next, and authors may have their works rejected. For example, Orwell's Animal Farm was once rejected with the publisher saying "It is impossible to sell animal stories in the USA". Clearly the publisher had an opinion on what kind of books are (not) profitable. With this new data publishers will have even more opinions.
