Their original purpose was to allow space for positioning errors of the paper on the printing press and allow space for the binding and final trimming of the edges of pages into books or magazines after printing the pages, so that all of the text would be visible and readable. Readers frequently scribbled notes in the margins while reading to record their ideas about the text.
