What is the best book on grammar

[JiriLindovsky]

Good morning,


would You please recommend me a book on grammar (with good index) for upper-intermediate. or advanced level on market. Something like MUST-READ. I'd like to improve my grammar by reading good explanations, examples and maybe "anti"-examples.
Does not matter if Oxford, Longman or whatever.

Thank You in advance,

Jiri Lindovsky

I like these: 'English Grammar in Use' by Raymond Murphy and 'Advanced Grammar in Use' by Martin Hewings. Both are published by Cambridge University Press.
