Before PDF: John Warnock's 'Camelot'

Karl De Abrew writes: "In the Spring of 1991 Dr. John Warnock wrote a paper he dubbed "Camelot" in which the Adobe Systems Co-founder and CEO laid out the foundation for what has become Acrobat/PDF. With the author's permission, Planet PDF is pleased to publish the full-text of that historic document." Of course, now it's 2002, and the dream of universal display / printing remains only partly realized; PDFs really have helped to narrow the gap between dream and reality, though.
