Proofreader Marks

A file I often need, and can rarely find. Maybe if I put it here I'll be unable to lose it--all I'll have to do is remember that if I google for "DeLong" and "Proofreader" I will find it...

Or so, at least, is the plan. I will (a) have to wait for google to find it, and (b) have to remember how I am supposed to search for it.
