The given plans demonstrate some major changes to a school library in the duration of 5 years. Overall, the school mostly renovated its library in terms of facilities while keeping the same size.
The most noticeable difference in the library was 4 studying tables in the center of the room, as 2 more were added as well as they were all divided into private sections instead of large whole tables. On either side of the studying tables, there were 2 long bookshelves. However, the one in the bottom of the map was removed to make room for student's laptops desks. In addition, other desks for laptops were added in the place of desks used for conventional computers. Also in the 5 year period, the library office has been converted into a conference room in the bottom right corner of the plan.
To the left of the studying area, some renovations could also be observed. In the lower corner, the library now has 2 separated borrowing and returning areas instead of 1 joined desk. Besides, there is now a recording room occupying the space used for a classroom, while the meeting room is still remaining.
