Copyediting
You have a complete draft & although you’re not done, you need a fresh pair of eyes to take care of the details you might have missed. Grammar, punctuation, sentence structure, consistency of details & facts, inadvertent repetition, basic fact-checking: all of this is covered by copyediting.
Proofreading
Aclose read focused only on catching large errors, such as misspelled words & glaring factual inaccuracies. Ready to submit your manuscript to a literary agent or publisher? About to self publish? Perhaps have it proofread first, to ensure it is in the best condition possible.
