“The Human Fear of Total Knowledge”, an excellent long article in The Atlantic for June 2016, which surveys the idea of “infinite libraries” in science fiction and fantasy.

Be warned that the article casually slips in a huge spoiler for two of the most outstanding episodes of the classic David Tennant years in Doctor Who, “Silence in the Library” / “Forest of the Dead”. These run a story back-to-back across the two episodes, and are well worth watching as your first-ever Doctor Who episodes.
