/lit/ - Literature

/lit/, is there a list of fundamental books? Not just great works, but works that permeate through literature by way of allusions and references. The most obvious would be the Bible but what else is there? What are the most common works that authors assume we have read? Like recently I read Frankenstein and it wasn't essential that I had read Paradise Lost before hand but it was definitely nice to get all the allusions, I want to be able to catch as many of these as possible. I looked at the Recommended Reading page and I don't think I see anything related there. tl;dr, fundamental works of literature so I can understand allusions and references.
