user703: 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 (it was updated during the time of version 2).
Is there anything newer?

user10687: This github post has links to polyglot books; the Komodo book looks especially enticing to me: https://github.com/michaeldv/donna_opening_books
