Небольшой (но очень полезный) вопрос, который не отнимет у Вас много времени.

 I use Russian (written by Russian authors) textbooks for learning English language, and you do the same as I think (use English textbooks for learning Russian language). And I want to know what are this books for understanding main problems of learning Russian by English speakers (and maybe it will help me to understand difficult aspects of English language). I don't think that this blog will find many answers but in any case I want (if you don't mind) your answer to contain at first the author of textbook, the name of textbook and the year of edition and if the book that you use already contains in another answer just make the comment in it, please (so we will able to identify the most popular book).

Thank you. Спасибо.
