As an important place for people to acquire knowledge, the library is always associated with the terms "seriousness" and "silence".

However, with the changing times and the trend of the future, the library is also adapting to the characteristics of the future. People who come to read no longer feel serious and depressed, but rather leisurely and entertained, enjoying the fresh, simple, and natural fun of modern life, feeling happy while reading and acquiring knowledge in happiness.

The building is a landmark of the city, and the library building skillfully combines knowledge with modernity, giving people visual enjoyment and spiritual pleasure.

For example, the Stuttgart City Library of Germany, designed by South Korean designer Eun Young Yi, looks like a huge white cube on the surface. The whole building consists of two floors underground and nine floors above ground to form a pure white space.

The circular, hollow and transparent design makes the space more open. There is a fountain of 1 square meter in the centre of the floor and a skylight above the roof. With a light blue sofa, it is simple and modern.

The Basconselos Library is also a world-famous library building, named after Jose Basconseros, a Mexican cultural figure, philosopher and politician, located in a botanical garden in the centre of Mexico City. it was renovated and put into use by a station in 2006.

Designed by architects Alberto Karachi and Juan Palomar, the library uses concrete and glass structures. The bookshelf looks as if it is suspended in mid-air, and it is also characterized by the huge whale skeleton in the centre of the library.

In addition to these conventional buildings, there are other more interesting libraries.

2. Bus Library

Sleep, and play with your cell phone, is everyone like this on the bus? There is a bus in Brazil with a mobile library in it. You can borrow it at any time, for the owner of the book doesn't care whether the other person remembers to return the book at all.

3 Mailbox Library.

Don't think that the library must be very big, as long as there is a mailbox at the door, you can transform it into a small library and share your favourite collection of books with the whole community. It is said that there are three or four hundred mailbox libraries like this all over the world.

4 Telephone Booth Library.

In Westbury-sub-Mendip, a small town in southern England, the telecommunications company wanted to remove the abandoned red phone booths, but the residents chose to keep them and found a new use for them. These phone booth libraries are open 24 hours a day, and all the books are provided by the town's residents.

6 Sod Library.

Twelve green bookshelves were placed in St. Peter's Monastery in Italy. It was created for the festival, on a piece of green turf that makes you feel like you're chewing words in nature.
