Professor Emerita Heather Jackson interviewed by Simon Armitage (BBC Radio 4, Marginalia)

“When someone takes a pen or pencil and adds a comment, an underlining or a question mark to the pages of a book – is it cause for celebration or condemnation? And if the person with pencil in hand happens to be famous, should that colour our view? These are the questions Simon Armitage – himself a lapsed margin scribbler – wrestles with as he sets off to tell the story of marginalia.”  You can hear the interview here.
