Emeritus Professor John 'Jack' Foster from Queen's University Belfast has returned a poetry book to the library an impressive 47 years late. 'The Poems of Arthur Hugh Clough" should have been returned in October 1966, and the delay should have cost the Professor £8,577.50.

So is this biggest library fine of all time - or the latest to be returned?
