Which do you want, the electronic library or the traditional library? I choose the electronic library. I am sure that the traditional library will be replaced by the electronic library. Some people like to enjoy their time in the traditional library. I object to its time-consuming search. Usually you can't find what you need because you are not familiar with this library or there is no such literature at all. On the contrary, with e-library, you can enjoy reading with your family at home, which is convenient for you to find everything you need, and e-books are environmentally friendly and sustainable.
