Raymond Murphy's legendary titles are known and loved the world over, and have given literally millions of students the tools they need to tackle English grammar head-on. Raymond taught English as a foreign language for 17 years in Germany and the UK, but since 1988 has been a full-time writer of EFL materials.
He is the author of the following best-selling Cambridge titles: Essential Grammar in Use, English Grammar in Use, Basic Grammar in Use, Grammar in Use.
I found more than 30 typos in the first brazilian edition and well, this is supposed to be a grammar book!!!
*update: I notified Cambridge about the mistakes I found and they not only promptely answered me but also sent me the third version, that I'm reading and couldn't find any typo so far. I recommend those who are looking for this book to buy this same version and choose the edition printed by Cambdrige (not the Martins Fontes one).
