If you take the subway in Madrid, you will probably notice some text fragments of Spanish literature hanging on the walls of the trains. You can even read fragments of Catalan literature that bring Madrilenians closer to the Catalan Spirit.
Passengers can keep reading by borrowing the book in the libraries located in some subway stations.
It is called Bibliometro and it is a free service to borrow books from the libraries that the city council of Madrid has brought closer to commuters.
These libraries are run with the same system as the ones spread in the city of Madrid.
You can borrow books during max.15 days and you can give them back in any of the ‘bibliometro’ stations.
