Grammars and things

One or two proficiency students have asked about extra practice for grammar or vocabulary work. Here are some recommendations.

Advanced grammars:
Advanced Grammar in Use - Martin Hewings (CUP)
Advanced Language Practice - Michael Vince (Macmillan)

A very good reference is:
Practical English Usage - Michael Swan (OUP)

Vocabulary:
English Vocabulary in Use Advanced - McCarthy & O'Dell (CUP)

Feel free to post other books here that you have used and found useful.
