Annotation Proof is a type of proofreading that involves checking for accuracy and consistency in the formatting of a document. It is often used in legal documents, such as contracts, to ensure that all information is accurate and consistent. The two most common terms used in Annotation Proof are STET and IBID. STET is an abbreviation for the Latin phrase 'stetit littera, ' which means 'let the letter stand.' This term is used to indicate that no changes should be made to a particular section of text. IBID stands for the Latin phrase 'ibidem, ' which means 'in the same place.' This term is used to indicate that the same text or reference should be used again in the same document.
