I uploaded the book "Upbuilders" by Lincoln Steffens. The OCR'd text quality is excellent, but it is offset by one page (preventing me from using the "Match & Split" tool to populate the pages). More details here: https://en.wikisource.org/wiki/Index_talk:Upbuilders_by_Lincoln_Steffens.djvu
I'm not sure whether this problem originates with the original scans at IA or with the IA Upload tool.
