Hi Julie, If a blind person scans a book that has things that they can't see which ocr poorly, they can do a couple things. One: they can put a comment in that alerts the validator that the book contained such problem items. Maybe somebody sighted like cindy will come along and take on such books, because they can fix them up to an extent that those of us who can't see simply can't do. Secondly, the blind person can clean out the junk that resulted from the attempted ocr of the graphs etc, so that the text which is presented is as clean as possible and does not contain a lot of junk that will seriously detract from others' ability to get value from the book.
