The document discusses three bookmobiles operated by the Lyon Public Library that provide library services to different populations. The first bookmobile serves urban areas with regular stops every two weeks and offers lending services as well as cultural and educational activities. A second bookmobile called the J'BUS targets children but is open to all, featuring a more modern design with multimedia options. It visits childcare centers and schools. A third future bookmobile will replace the aging one serving retirement homes and aim to better support events and festivals with a modular and mobile design inspired by pizza trucks.
