You are more worried about books then the message in the books.
Thousands of years back people used to write on stones. Then they started writing on leaves. Afterward on some other things. Then there was a age where paper came into practice. Now there are ads saying "Save paper Save Trees."
Today we have online books and online libraries which has made easy to access the books world wide.
Using Internet or other electronic media is not a bad Idea, what is important is the knowledge.
In Ancient India the sacred texts were transferred to their disciples by their Gurus, So there was only soft copy. Don't expect a pen and a paper 7000 years back.
Today we are only using technology to store data. Tomorrow there might be something else like the film "The Matrix" where you directly feed data into the brain.
In short do not worry about books. You have to see what knowledge they offer.
