The two maps illustrate the transformation of a floor in a public library, which has undergone significant changes over the past two decades.
Approximately 20 years ago, the floor plan featured tables and chairs at the center. To the left and right of the central area were the adult fiction and adult non-fiction sections, respectively. An enquiry desk was situated on the right-hand side of the entrance, symmetrically opposite a reading room that housed newspapers and magazines. Behind the adult fiction section was a room containing CDs, videos, and computer games, while the area behind the adult non-fiction section was dedicated to children's books.
Following the renovation, the central tables and chairs have been removed. The enquiry desk has been replaced with a café, which is now complemented by three new self-service machines. The reading room has been transformed into a computer room, and the children's book area has been converted into a lecture room. Additionally, the gaming room has been redesigned as a children's fiction book section, complete with two new sofas suitable for hosting storytelling events.
In summary, the floor plan of the public library has seen several functional changes, and new facilities have been introduced. The modernization of the library has been evident through the incorporation of contemporary amenities.
