Love this. The top programming books being SICP, Clean Code, and Crafting Interpreters feels very on-brand for HN.

Surprised by how much fiction shows up though. I'd assumed HN skewed heavily technical but seeing 1984, Dune, and Foundation in the top mentions suggests the community has broader reading habits than stereotypes suggest.

One bug: looks like "The Martian" by Andy Weir is getting grouped with "The Martian Chronicles" by Ray Bradbury. Might want to add some disambiguation logic for common title collisions.

How are you doing the extraction? LLM-based NER or something more traditional like regex + entity matching?
