very helpful in the way it is laid out. by that I mean in each subject it lists the :Old Testament then : New Testament : Ancient Near Eastern World : Greco-Roman World :Jewish world :Christian world I absolutely love this format. it makes it incredibly easy to find what your looking for and also has a good bibliography for further study. Is it worth the money? I'd say it feels like a mini expansion pack to the Anchor Yale Dictionary. I think it's worth it for what you get. Originally I thought there was not enough content but it does contain a decent amount.
