This is yet another book ranking but only Polyglot Books. It took me some time to collect all these books.

If you are interested in testing your polyglot book, I can include it futures cycles. There is no limitations by Author.

I am still structuring some rules and if it becomes too complex, I will simplify into a more simple rating list for Polyglot.
