Best Writing Guide for ESL Students

I currently have an advanced ESL student who wants to improve his writing skills. He has also asked for recommendations for books to buy before he returns to his home country. English grammar books and English books, in general are obviously easier to buy here in the U.S. than in non-English speaking countries.

Among the other books that I recommend to ESL teachers and advanced ESL students, I also recommended the classic Strunk & White’s, The Elements of Style.

Most of you are probably familiar with this little gem of a book. For those of you who aren’t, it’s a great little book of English writing rules. It’s short and small and pretty complete. I don’t know if this is a typically recommended ESL book, but I think it’s very useful for advanced English language learners.
