/lit/ - Literature

What are some short classics I can read? I usually read a shorter book in-between two longer ones, but I've run out of ideas. So far I've read The Great Gatsby, The Crying of Lot 49 and The Trial (along with many other of Kafka's novella/short stories). Ideally, no more than 250 pages.

Can someone explain to me how this novel incorporates the idea of Existentialism in any way?

Are there any translations of "The Trial" that actually follow any sensible standards of style? The gigantic walls of text in this edition are completely unreadable. I'm not exaggerating when I say that if one of my freshmen submitted something to me with this level of organization and lack of proper style, I'd fail them for the semester. And I teach mathematics, so I already don't expect much out of the little idiots.

Pic related, it's the version I bought.
