The book was originally conceived and edited by James Marriott (who also contributed most of the reviews), with ten essays by Kim Newman. Marriott died in 2012, so the additional reviews in the third edition were all written by Stephen Thrower. For this year's edition, the new reviews have all been written by Owen Williams. Whereas the first edition was published in hardback, with colour photographs, the images in the subsequent paperback editions are all black-and-white.
