I have recently tagged a few resources "Big Picture" (mainly, "Exploring the Old and New Testament Collection") and added them to my passage guide with the idea that I could see where in the biblical story the passage falls and utilize some awesome resources (I am working in Nehemiah). So far it is pretty "hit and miss", but the idea of a data set that would "peg" the events into a broader picture AND have links to resources that give more info sounds helpful.
What do you think?
