Thomas Harding at Literary Hub:
Lolita was originally published as a limited edition in France in September 1955. The book was released by Maurice Girodias of Olympia Press, a company known for specializing in pornography, but which had also built a reputation for publishing challenging literary titles. The first print run had been 5,000 copies and the book received little attention.
Over the next few months, a handful of copies of Lolita were smuggled into England. A single copy made its way into the hands of Graham Greene, who reviewed it favorably in the Sunday Times. This was followed soon after by a scathing article in the Sunday Express, which denounced the book as “sheer unrestrained pornography.” Shortly after, the British Home Office ordered that all copies entering the country should be seized.
