Electronic or paper books...Ok,let's talk about it,let us pass to the main.Firstly i think that books have an important place in our life. Because with their help we can know more and more new information.And of course this will all be useful for us.And now there are two  kinds of riding.We can read them live  or read them in electronic view.One of the reasons for this is that if you read a book live then you can worry about the heroes because it's all so natural .I think it is more interesting to read  books live than in electronic view.And that is why i prefer to read books live.
