Sorry, not completely true. For most books 300dpi would be sufficient, but it really depends on the source. I scan at 400dpi and get a lot less OCR errors, especially with older pockets and paperback. Everything over 600dpi would be overkill. Downside is the decrease in scanning speed. I find that 400dpi is a good tradeoff.
