Comments.Text: @StudentT thank you. Did no know about polyglot format. Actually was not able to find a normal book based on similar to yours searches (the best one was 1.4Mb, whereas my old stockfish book is 5.8mb).

Comments.Text: The best chess books are designed for the Chessbase and Hiarcs format. The largest Polyglot books are usually bundled with a chess engine. I don't want to search every engine site, but I have seen it. You could build your own book. It's easy, this way you can turn a 100GB database into a gigantic book.

  (Asked by: username_0 on 2014-12-04)
  
  I am looking for a relatively up to date opening book for stockfish5 chess engine. I do not need it to be created by a stockfish team (only to work together with stockfish).
  
  Up till now the only thing I was able to find is [really old book](http://support.stockfishchess.org/discussions/questions/767-opening-book) (it was updated during the time of version 2).
  
  Is there anything newer?
