If you have books piled up at home that you enjoyed reading but now you don’t know what to do with them, you can put them in bookcases set up near the guard’s office of your apartment building. You can also borrow books from other residents.

This is the idea of the “Sharing City,” where people share things, space or information which they possess but are not using.

Seoul Metropolitan Government said Thursday it will promote the idea to raise the social value of individuals’ goods, space, time, information and abilities by facilitating the process of sharing without causing a burden.

“The world is paying attention to an economy based on sharing, not possession. By expanding the sharing culture which we used to have in the past, community culture can be revived. It can also help us save social expenses spent for safety and welfare,” Mayor Park Won-soon said in a press briefing.
