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 Franz Schubert, Robert Fulton, William Kent, Johann Wolfgang von Goethe, Antonio Vivaldi, James Cook, Hugo Grotius, Francis II, Fyodor Dostoyevsky, Joseph Scaliger, Edmond Halley and Gilbert du Motier. 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?
