The graphs illustrates information about a public library floor plan from 20 years ago and how it seems now. The most significant change that can be noticed is that there were tables and chairs in front of the entrance from 20 years ago but now they eliminate these things and the entrance becomes free from any objects.
Central library 20 years ago, there was a room in the east side next to the entrance for enquiry desk but now it is changed into cafe. The next room in the same side was children books rooms , although now it becomes a lecture room. Between these two rooms there is a colidor, 20 years ago was for adult non-fiction books , now it is for information desk,self-service machine and adult fiction books.
On the other hand, the left side,the first room near to entrenc was a reading room now it is a computer room. The second room was for CDs, videos and computer games. Now it is a chamber for story telling events. The colidor between them was for adult fiction books. Now they are all reference books.
