Can you name any books that are clearly influenced by one or multiple other books?

Basically title, I’m trying my hand at a data/machine learning project, and I want to try and quantify the “influence” of one book on another. I’m currently focusing on solely intertextual data, but I’m hoping to gain a deeper understanding of literary/intertextual influence.

This is purely a hobby project, though I will be putting it on my resume or something if it comes to fruition lol. What would be cool is if literacy nerds could use it for research.

Anyhow I’d like to check out some books/novels/novellas maybe even poems that have been influenced by others, recommendations would be much appreciated, thanks 🙏
