　　The university has decided to offer reference material online because paper, newspaper and journal take up too much space.

　　The man agrees with the decision.

　　First, he thinks the library has no space to keep the books and the school has to expand library by building a new building. But online materials could help solve the problem, which is more economical.

　　Second, students have computer in their dorms and it’s convenient to search the material online.
