Overall, it can be seen clearly from the provided information that significant changes are made to use floor space in the school library. There are more table for studying and more desks provided for students to use their laptops.

Five years ago, there were only four tables in the middle of the school library which were used for studying by pupils. However, the floor space nowadays are supplied 36 differents tables that students can learn in privacy. The bookshelves at the top of the old plan still remain until now, but the second one at the bottom of the plan five years ago have been replaced by the desks for students' laptops. Naturally, computers today are not as popular as laptops; therefore, the desks for computers are also used for laptops of pupils.

During the next five years, the library office has been converted into the conference room, and the classroom has been transformed into the recording studio. Interestingly, the borrowing and returning ares are now separated. The meeting room which is located between these spots has till been existed.
