An errata is a loose slip or a tipped-in page added to a finished book to correct mistakes discovered only after the main press run was completed. It lists the page number, the error, and the correct text. Publishers use errata slips as a last resort to fix critical errors without the massive expense of reprinting and rebinding the entire edition.
