Ok… recognizing that improving quality of the historical county boundary relations of the United States will be an ongoing project, and… recognizing there are likely errors here and there in this effort that will need to get cleaned up after the fact, and… recognizing that nothing on this project is ever really “done”… I’m going to take the bold step of saying…
the import of the Newberry Library’s Atlas of Historic County Boundaries is done. : )
Time to put a bow on it 
.
Newberry is done!
Long live Newberry!
Wait… what?!?
Well, like @Minh_Nguyen pointed out above, everything still on our to-do list, still needs to get done to make sure we have the most up to date and robust dataset of historical county boundaries on the web. It’s really just the first phase that’s “done.”
Long live Newberry!
