Can I Leave a Note When Scanning a Book

Yes! If you need to note that a book has a misspelling by the author so the proofreader doesn't correct it, by all means do so. Make sure to do so by writing "Scanner's Note" in brackets though so the proofreader knows what it is!

These notes must be deleted out of the file before the file is checked in by the proofreader.

Here's an example:
