Just when you thought you couldn't get enough of your favorite papal encyclicals . . . uh . . . this nifty site has catalogued them all, for easy access online.
N.B.: My American friends who read this blog might want to read Pope Leo XIII's encyclical Testem Benevolentiae Nostrae, regarding the dangers of Americanism, which he addressed to Cardinal Gibbons of Baltimore in 1899. Some very interesting and pertinent stuff there, I'll tell you.
