Can you help to describe the events, people, etc, surrounding Lolita (the book) NOT being banned in the US?

I am writing a paper which is meant to give a stereoscopic view of Lolita: it’s publication in France in 1955 and then it’s publication in the US in 1958—it was widely thought that it was going to be banned in the US, but it was not.

Can you speak to this time period, obscenity and censorship, etc?

(p.s. what an incredible read….)
