My job involves correcting grammatical and spelling errors, while copy-reading involves looking at the work and fixing any problems with style and tone. Copy-editors usually do fact-checks as well, making sure that everything in the text is accurate and true. A proofreader ensures content is free of typographical, grammatical, spelling, punctuation, syntax, formatting and other such errors. The job is all about tweaking the syntax and diction in a piece to ensure the most fluid, original projection of the content possible, This is the person who notices the extra space after a period, the “their” when it should be “they’re” and the compound adjective missing a hyphen.
