Yes, fallen books may be a minor tragedy which I'm sure all photographers can relate to. Books are precious. But compared to what happened in Haiti, the subject seems perversely unimportant. Those folks aren't worried about a few overturned shelves. They're sorting through corpses.
I don't think the timing was intentional. My guess is that Ladd had the review in the pipeline that day and posted it before hearing about the Haiti quake. But a week later, it's still hanging out there in cyberspace like some slightly rotten fruit, attracting no comments, waiting to be reshelved.
