The more liberal use of paper at the beginning of the fifteenth century by this newly created class of readers and book-buyers marks the period of transition and of mental and mechanical development for which the crude arts of paper-making and of block-printing had been waiting for centuries. We shall also see that if paper had been ever so cheap and common during the middle ages, it would have worked no changes in education or literature; it could not have been used by the people, for they were too illiterate; it would not have been used by the professional copyists, for they preferred vellum and despised the substitute.
