This is a re-posting of a HathiTrust blog post. HathiTrust receives well over a hundred inquiries every month about quality problems with page images or OCR text of volumes in HathiTrust. That’s the bad news. The good news is that in most of these cases, there is something they can do about it. A new blog post is intended to shed some light on the thinking and practices about quality in HathiTrust.
