What is the difference between the bible books of Sirach and Wisdom?

Many differences could be pointed to. The one that stands out for me is that The Bible requires no correction or alteration. People allege all kinds of errors in the Bible, but under close scrutiny they turn out to be either a mis-understanding or mis-quotaion. In contrast, works of purely human origin can be in error. There are miles of shelves in libraries where scientific facts previously thought to be correct have been shown to be in error. The Bible accurately describes the human condition, warts and all ,as well as the way to get things right and restored again.
