20 years age, there were 2 ailes in right and left of the entrance, the left one was for adult fiction books and the other was for adult non-fiction books. Today, the left aile is for refrence books and the right one is for fiction books. In addition, near the fiction books, an information desk and 3 self-service machines are added to make the whole area more practical. In the past, in the middle of library, the area furnished with tables and chairs which now are removed completely therefore the accessibility to other areas increased.
