Is editing the same thing as
proofreading?
Not exactly. Although many people use the terms interchangeably, editing and proofreading are two different stages of the revision process. Both demand close and careful reading, but they focus on different aspects of the writing and employ different
techniques.
Editing
Editing is what you begin doing as soon as
you finish your first draft. You reread your draft to see, for example, whether the paper is well-organized, the transitions between paragraphs are smooth, and your evidence really backs up your argument.
Proofreading
Proofreading is the final stage of the editing process, focusing on surface errors such as misspellings and mistakes in grammar and punctuation. You should proofread only after you have finished all of your other editing revisions.
