Of course the amazing thing is that the analysis of this new binary pulsar improves what was an already compelling comparison in 1993. I know I've linked to it many times before, but forgive me if I direct people once again to the Particle Data Group's review of Experimental Tests of Gravitational Theory. It's intended for physicists and astronomers, so some may find it hard going, but its summary of the current state of tests of GR (complete with references to the original papers) is useful.
