Nick Hornby's novel Fever Pitch is being republished as a Penguin Classic.
Author Fay Weldon, describes a classic novel as a book which makes sense in any century you read it in but says it is often a novel "you ought to read" rather than "you want to read".
John Sutherland, professor of English Literature at UCL, says the classic novel is a "very loose category" but also an important one.
"People want a bit of guidance as to how they're going to invest their time," he told the Today programme.
