Map links across a nonfiction library

Point an agent at your book folder and have it surface themed links between excerpts from different nonfiction titles.

Done with Claude Code· Intermediate

What they did
Pieter Maes gave Claude Code access to a personal nonfiction library. The agent searched across the books, then sorted matching ideas into named trails with a short claim, connected concepts, and the titles behind each trail. The results were published on a browsable site with a book index.
How it went
The site ended up with dozens of trails, including Useful Lies, Pacemaker Principle, and Proxy Trap. Each trail ties together five books that usually would not be grouped together. The page does not explain how those links were verified.
Tips
If you try this, read the linked explainer first so you understand the method before copying it. It also helps to decide in advance which folder, file types, and theme you want the agent to search.

Try it yourself with Claude Code

You are looking at my personal library of [number] nonfiction books in [file types] at [folder path]. Build an index so you can search across the whole library, then find [number] distinct trails that connect books around [topic or question]. For each trail, give it a short title, write one sentence stating the central idea, list the related concepts, and include the books and excerpts you used. Before you do anything that would change, publish, delete, submit, or send files, stop and ask for my approval. Then present the trails in a format I can review or turn into a browsable page.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
