Taking inspiration from New York City's underground library, the Beijing Metro Transportation Railway (MTR) created the M Subway Library. The public welfare program allows passengers on the Line 4 subway in Beijing to borrow eBooks inside train cars by scanning QR codes. The initiative was established with the help of the National Library, who provided the literary resources for riders.
Perfect for commuters, the underground library helps support culture and encourage reading and learning according to China's National Library Deputy Director Lee Honglin. The public transportation-based library uses public space to inspire people to read more and integrate knowledge into their everyday lives.
A similar library has been established in Shanghai on the Metro Line 2, where bookshelves are installed at stations.
