You can read all the accident and first ascent reports on their website for free, you just have to be a member or buy if you want the hard copy. They do a pretty good job of covering everything that is related to climbing or mountaineering but don't include hiking or lost persons reports.I think you are talking about the American Alpine Club accident reports(?). They are still done, but you have to be a member or buy:
