When it was originally launched in 1969, the Booker Prize (now the Man Booker Prize, in honor of the ), was retrospective. That is, 1969's prize was open to novels written only in 1968. Two years later, the competition was reorganized to feature the current year's writing. In effect, then, there was no award for novels written in 1970.
To rectify the situation, a list of 22 novels written in the missing year has been posted at the MPB's website. A shortlist will be announced in March, and the world can vote until May when the winner will be announced. Details and the complete list of nominees are here.--David E
