This is the first generation of Hugo's Three months, more focused on grammar and translation exercises (from L2 to English). A serious study of these books may give a good foundation and working knowledge of foreign languages.
This old Hugo's Three months series are available in French, German, Spanish, Italian, Portuguese, Dutch, Norwegian, Danish, Swedish, Russian and Latin(!). It would be a dream to have all these ones here one day.
N.B. Unfortunately the few pages on pronunciation are missing but nowadays there are better ways to learn proper pronunciation and the value of the book is the grammar part.
