Passage: The selection process for the winner of the prize commences with the formation of an advisory committee, which includes a writer, two publishers, a literary agent, a bookseller, a librarian, and a chairperson appointed by the Booker Prize Foundation. The advisory committee then selects the judging panel, the membership of which changes each year, although on rare occasions a judge may be selected a second time. Judges are selected from amongst leading literary critics, writers, academics and leading public figures.
