Proofreading marks are used by proofreaders and editors to indicate an error in the copy. The nature of the mark is directly related to the type of error that has been produced, and proofreaders and editors will place the proofreading mark in the line of text where the error takes place. Depending upon the nature of the editing services, the proofreader will then either write a correction in the margin or will write a correction directly above the sentence.
We have a free guide to basic proofreading marks available, and you can download and print the PDF version from our account on Scribd:
Proofreading Marks at Vappingo
Here at Vappingo, our proofreaders and editors do not use proofreading marks because we favor the more modern techniques of correcting errors. Our proofreading services involve the editor correcting the mistakes using the track changes functionality on Microsoft Word. Once the proofreading is complete, our customers are sent two copies of the text: one that contains all the corrections in their final form, and one that shows where all the corrections have been made.
