This handmade bookmark has been modelled on a surviving 15th-century bookmark held in The Newberry Library (Case MS 37.5). Originally made in scriptorium offcuts of vellum or parchment, this modern version is in animal-friendly, parchment-effect, card and is handsewn with linen thread. The bookmark moves up and down the cord to show how far down the page you have read. The revolving disk displays roman numerals I-IV. Originally designed for books with two columns a page, this would show which column or section you had reached on an opened spread of 2 pages.
