It will not attempt to sell you anything. The link to where you can buy Father Sebastian Englert's Island at the Centre of the World is there because this is the best book in English about Easter Island, not because we might receive a commission (3 to 4%) on sales.
The link to Les Mystères Résolus de l'Île de Pâques is there because, without the generous input of the Centre d'Études sur l'Île de Pâques et la Polynésie, rongorongo.org would not exist.
