Linguistic proofreading is essential in the publication of a text, its preparation. The act of correcting a book, a letter, or any type of document implies that the original text must be respected as to the author's style, but spelling, syntax and style issues must be modified if necessary. Thus, the task of a proofreader is to ensure that the final text is entirely correct.
When Torsitrad has to correct a document, it always does so in the format that the text was sent (with a final review of the document prior to sending it to the author/client). Then, once the author gives their approval, he/she would review the page proofs to ensure the highest quality.
