I spent the day yesterday editing and proofreading a manuscript before turning it into my editor. I went through this draft on paper and made marks in ink.
Years ago I attended a workshop on the Chicago Manual of Style. It made me wish I paid more attention back in high school English class. I learned a lot in the workshop, but the thing that stuck with me the most was the proofreader’s marks. Working at a publishing company, we use these marks as a universal language for corrections to books and marketing materials.
I thought it would be fitting to post those marks today:
