Businessman Nader Riad has set up street libraries around Cairo, according to TRT World. The premise is modeled on the Little Free Library system: Set up a few cabinets to serve as book shelves and ask the public to stock them with books they don’t need. The libraries then run on an exchange system where people place a book before taking one that they want and the libraries become automated. In a city as big as ours, there is bound to be at least a few dozen books being hoarded, and Riad is hoping to get them into his street libraries. Three of them have been established so far with more coming over the next few months (watch, runtime 2:27).
