The diagram below shows the plan of public library 20 years ago and how it looks now. Summeriz the information by selecting and reporting main features, and make comparisons where relevant.

The maps demonstrate how the inner space of the public

library

was modified over a 20-year period. Over the past 20 years, the

library

floor, which has four main rooms on its corners, saw spectacular evolutionary changes and many new facilities have been established. The lecture site, Café, computer area, information section, and self-service machine facility were not available 20 years ago in the

library

;

however

, the entrance doorway is still located in the southern part of the building as it used to be.

Furthermore

, some sections of the

library

just have been relocated. The reading area, the southwestern part of the floor, altered into the computer area,

also

its door is now on its right side. The CDs, computer games and videos were kept in the northwest room, but today

this

field was altered into the storytelling field and children’s fiction book storage.

Additionally

, it is enlarged downward in size. The northeast room used to be the region for children's books;

however

, it is a lecture room now.

In addition

, some pieces of equipment have been omitted. The tables and chairs that used to be in the middle of the floor are now eliminated, and the doorway of the northern rooms is the same as the main entrance door.
