These are the differences between editing and revising. When revising you look over the paper for mistakes, and for better ways of stating things. When editing you actually fix your mistakes and things are stated differently. I believe editing to be used mainly on finished papers and books. The changes on the finished product is editing.
Revision is changes done on work in progress.
When Revisingt a paper, you are going over your work, checking for any mistakes. When editing a paper you are taking out parts you do not want anymore, as well as adding peices not previously considered. Editing is changing a few things in a writing while retaining the major idea. Revising is making many changes which may change the main idea. Editing is the making of corrections of words, sentences and puncuation.
