I know it wont be me , I have between 250-300 books on chess.
Are you being sarcastic here or do people actually own more books than you? The only way you can own this many books is to just purchase the sea of opening books people make in their sheds over a weekend. Then again, I suppose it depends how many languages you can speak...
I own no books at this moment in time. However, after Christmas, and my January birthday, I shall own all of five books- My System, Winning Chess Strategy, Winning Chess Tactics, Winning Chess Endgames, and Jeremy Silman's Complete Endgame Course.
Not the biggest collection, which was the point of this thread, I believe, but a collection which (I hope!) covers everything I need to know.
I thought it would be interesting to know who on chess.com has the largest personal chess library. I know it wont be me , I have between 250-300 books on chess. Are you the one with the largest library here ?
