Peer-reviewed open textbooks with free PDF downloads. One textbook chapter per source works well.

These are peer-reviewed, openly-licensed textbooks, which makes importing one chapter at a time more reliable than piecing a subject together from scattered web pages of uneven quality. It's a strong fit for a notebook covering an intro-level college subject like biology, economics or chemistry. Its catalog stops at the introductory level, so it won't help with anything upper-division or specialized.

## Import into Gemini Notebook

1. Copy the link: https://openstax.org/
2. In your notebook, click Add source → Website.
3. Paste the link and confirm — several links can be pasted at once, one per line.

**Tip:** Lecture notes and open textbooks are the highest signal-to-noise sources for studying — often better than the slides you were given.
