This is an English textbook I used when I studied abroad in the Philippines. It's printed, but the content is the same as a regular book. The email writing guide is a bonus. A self-study reference book for English learners. A textbook for a deep understanding of grammar. - Title: Advanced Grammar in Use - Author: Martin Hewings - Edition: 2nd Edition - Language: English - Format: Self-study reference book - Publisher: Cambridge University Press - Bonus book: Eibun Mail Kyoka Juku (English Email Enhancement School) Thank you for looking.
