Entertainment / Literature / Catchword: This phrase comes from printing, it refers to a trick printers would use to keep pages in their proper order. The printer would print a specific word below the text at the bottom of a page. This word would match the first word on the next page. A printer could thus check the order by flipping quickly from one page to the next and making sure the catchword matched appropriately. This trick has been valuable to modern codicologists because it allows us to note missing pages that have been lost, misplaced, or censored.
