Did Vladimir Nabokov deliberately take the idea for Lolita from a 1916 short story of the same name or did he suffer from cryptomnesia? Cryptomnesia is when you consciously forget previously learned information but subconsciously remember it.

I feel like I've pointed to this before, but in case I haven't, here's a list of the 100 best first lines from novels. I'm partial to those of Pride and Prejudice, Lolita, and Anna Karenina.
