I was just thinking that it is possible to make the whole books of Russian poetry and other stuff with stress marks above the words. Perhaps having such texts is a good way to improve your pronunciation and reading skills. And you don't have to look into a dictionary every time you don't remember how to pronounce something. But, from the other side, you may become used to such a books and will not be able to read normal texts properly. So, what do you think of it, and do you know whether such texts already exist?
