It is always good practice to revise and if necessary completely rewrite text in documents to ensure that they are accurate, concise, and the best they can be. Straightforward you might think and you might say “What could possibly go wrong?” Quite a lot actually. But in the process of review there are some hidden traps an author can fall into when using Find and Replace, or inserting or deleting text that can affect pagination.
Proofreading is the last stage of the editing process for a document and should only be carried out once all other revisions by the author / contributors and amendments by the copy-editor have taken place. Proofreading therefore has an important role in publishing and business as it is the last chance to correct any errors before the book or document is published.
