Yes, Christina, OCR errors definitely need to be corrected. The problem is that many books have at least one error and without the print copy of the book and some sight, a validator won't know if it is an OCR error or just a book error. But the number 1 for the letter I is almost always an OCR error. A book I am scanning right now just used the word sooth for soothe. I have to leave that as it is. A validator may change it unknowingly, but it's supposed to be left the way it is in the print copy. That was my original question in wondering if [sic] should be added. If I were to quote this book I would be required to add [sic] after the error to show the error was in the source and not my own error.
