I think I've trimmed out all the non-history, non-archaeology topics from the huge list from the keyword "exodus". Most of them were about the 'exodus' from this or that state of the union, or this or that counry, or this or that denomination.
Step three, of course, will be to combine "theexodus" and "exodus" as edited, to trim out the duplicates and produce a single comprehensive list. Don't hold your breath. :^)
