Ben:
I haven't looked closely at the UBS data, but i suspect this is just
an error.
I looked at a subsequent entry (Pisgah), which had the right number of
references, and the right books for them, but the chapter and verse
indices didn't look right.
As another source, you might consider the Proper Names dataset (http://
www.esv.org/
assets/blog/2008.04.data.capitals.txt) from
the ESV. I'm hoping we can accomplish some integration across these
various data sets in the future.
