A Dictionary of the Booksellers and Printers who Were at Work in England, Scotland and Ireland from 1641 to 1667/Chetwin, or Chetwind (Philip)
CHETWIN, or CHETWIND (PHILIP), bookseller in London; Next to the Black Horse in Aldersgate, 1670 (1656–74). Married the widow of Robert Allot, 1626–36, and so became possessed of certain copyrights in various Shakespeare quartos. In 1663 he published the third folio, and followed it up with a re-issue in 1664, to which he added the seven spurious plays, no doubt with a view to increasing the sale. His address has not been found before 1670. [Arber, Term Catalogue, vol. i.]
