All 7 of the Reykjavík city library will be running a book market during the whole week. The market is called Green Book – Good Book and has been going on in some of the libraries earlier. During the week the project will be introduced to all the libraries. Citizens can bring books they’ve already read (some restrictions are about conditions etc.) and swap them with books they are interested in.

The libraries will also have a special emphasize on books on waste prevention, sharing economy, reusing and recycling.
