Correction is about the corrector's work. Their main task is to check if there are any errors in the texts before their publishing. Notice that correction does not verify the accuracy of the content.

Revision, in turn, is a much wider task. It ranges from the evaluation of the texts before their edit to the publicity of a book collection, as well as the verification of a text accuracy, including spelling, grammar and other correction items.
