Thanks to Leanna's relentless capacity for toil, bless her, we are in better shape. I should be able to complete the PB tags for the remaining 1858 XML files by, roughly, April 20th, possibly sooner.
From there, I will process the images for 410/1, which should take a few days. Then, I will move on to tagging people and places in years 1852-1857 inclusive--as 1858 is, presumably, done already.
