The AMS Notices are now freely available online. Nice summary article by Brian Conrey on the Riemann Hypothesis, including the recent links with random matrices mentioned. His own work is not a reference in the survey article, but Conrey is the one who showed that at least forty percent of the zeros in the critical strip lie on the line with real part 1/2. See
