Sometimes I get confused over where a book is in the Old Testament.  This is because in my studies I have used three different versions of the Old Testament/Hebrew Bible.  The TANAKH is the Hebrew bible.  The Protestant OT is what we find in most English language Bibles.  The LXX is the Greek version of the Hebrew Bible.  So here is a chart of the order of books in each of them:
