Reasons

I think there are many complex reasons for some book selling well. It's not just by good manuscripts, good editing, a good market, or even a good planning. If we flatten such backgrounds, we may be failed to make a well selling book next time, though I don't regard it as the only goal of publishing book. By the way, I usually doesn't apt to publish a translation of a title in which many bloggers interested, at least by the reason of that.
