I got plenty of books.....all of them are dear to me.........and I would really like to keep it for ages ......to pass it to my offsprings......so that family library go on and go on the existence. But being able to keep it for so much time.......I would definetelly have to provide the perfect conditions to my paper treasures. So I got an idea about designing the perfect book case....that will be closed with the glass and inside there will be ab automatic system creating the optimal environment considering the temperature and moisture. Dunno I think this is something that is have to be designed for sure.
