Held in Special Collections, Lady Plowden's papers are an extensive and rich resource reflecting her many areas of concern. Lady Plowden held a number of high-profile public roles in the spheres of education reform and television broadcasting, most notably as Chairman of the Central Advisory Council for Education (England), 1963 – 1967, Vice-Chairman of the BBC Board of Governors, 1970 – 1975, and Chairman of the Independent Broadcasting Authority (IBA), 1975 – 1980.

Brian Alderson (b. 1930) is a pioneer of children’s literature studies in Britain as a distinguished author, reviewer, and translator. He has also collected books for more than 60 years, beginning when he was an undergraduate with cheap editions of work by poets Ezra Pound and T.S.Eliot. His interest in children’s books came later but soon became a lifelong passion, resulting in the curation of a collection of over 20,000 books, dating from the 17th century to the present day. This collection, donated jointly to the University and Seven Stories: The National Centre for Children's Books, represents a vast and diverse distinctive resource.
