The paper industry in England was then in its infancy and the quantity of quality rag paper for the book was imported from France. It is thought that the typesetting and printing of the First Folio was such a large job that the King's Men simply needed the capacities of the Jaggards' shop. William Jaggard was old, infirm and blind by 1623, and died a month before the book went on sale; most of the work in the project must have been done by his son Isaac.
