Camels are used by the Kenya National Library Service in North Eastern parts of the country to serve people living in nomadic settlements. In a region characterised by harsh climatic conditions, bad terrain, and poor transport infrastructure, the camels carry books to children, adults, and community health workers who would otherwise be unable to access any library.
