On going freelance in late 1976 connections with authors made at the BBC were sustained. Through Kenneth Clark Campbell did work for John Murray for whom he designed Clark's post-Civilisation titles and Reynold Stone's Engravings. He worked with Diana Souhami who had been a colleague at the BBC on a number of books including her Whitbread biography prize-winning Selkirk's Island. He first met David Sylvester when working at the BBC and went on to design books Looking at Giacometti, two collections of brief pieces, and the catalogue for Francis Bacon: The Human Body, an exhibition at the Hayward 1n 1998. He continued to work often with Quentin Blake and contributed the introductory note to Blake’s The Life of Birds.
He styled or restyled a number of magazines, for example, the Musical Times and New Left Review.
