The Booker Prize for Fiction was established in 1969 and awarded yearly to the best original English language novel published in the United Kingdom.
Until 1970 only books published in the previous year were eligible for the award.
For 1971, the rules changed to so that only books published in the current year were eligible for the award. This meant that books published in 1970 missed out on a chance to win the the award. In 2010 this was rectified by awarding the Lost Man Booker Prize to a shortlist of books that missed out.
