No matter what kind of content your company produces, someone is writing it, and that someone has questions:
—Do I need permission to quote this? To use this image?
—Is it 10 AM or 10:00 a.m.? 50km or 50 km? Forty euros or EUR 40?
—Can I cite more than one source in a footnote?
—Who or whom? James’ or James’s? Principle or principal?
—Does the comma go inside or outside the quotation marks?
