Printed mistakes, also known as ERRATA, are errors that appear in printed material such as books, magazines, and newspapers. These mistakes can range from typos to incorrect facts or figures. ERRATA is the Latin word for 'mistakes' and is used to refer to a list of corrections that are published after the original material has been printed. This list is usually included in the back of the book or magazine and is used to correct any errors that were made during the printing process.
