The web is a book with many secret pages written in invisible inks, a mountain full of caves where ancient scrolls lie hidden in shadows, a city where nobody knows everybody but everybody knows somebody. Recent successful quests were for James Ussher, Edward Jenner, Horatio Nelson, Charles-Louis de Secondat, Carlo Goldoni, Eduard Douwes Dekker, Bertrand Russell, Adam Smith, John Smith, Jacques-Louis David, Michael Thonet and Leonhard Euler. Various criteria can optionally be selected to finetune a search and speed up the arrival at the desired discovery. What might our visitors be looking for today?
