instruction: Give me a list of books that are long and hard to read. The sort of books with which I could impress someone who read a lot.
response: When talking to someone well read, I would go with some of the classics of literature. The following books require a very detailed read in order to be able to understand them, due to the complex topics they analyze. They are long, but also considered masterpieces:
  
  - "Crime and Punishment" by Dostoievsky
  - "Ulysses" by James Joyce
  - "The Magic Mountain" by Thomas Mann
  - "Gravity's Rainbow" by Thomas Pynchon
  - "Don Quixote" by Miguel de Cervantes
  - "Infinite Jest" by David Foster Wallace
