How to Add Free Textbooks to Gemini Notebook

Google expanded Gemini Notebook on October 29 so students can add hundreds of free textbooks as sources. Once added, every answer stays grounded in the book, with inline citations and links back to the original pages. You can also turn chapters into study guides, quizzes, and flashcards without uploading your own files.

This builds on Expert Intelligence, which already let users add eligible ebooks bought from Google Play Books. The new catalog covers providers in the US and India, including OpenStax, the Open Textbook Library, and S Chand Publishing. Access is free inside Gemini Notebook.

Why textbooks as sources matter

Gemini Notebook only answers from the sources you add. A textbook gives you a trusted, fixed corpus for a course. Citations point to specific passages, so you can verify formulas, definitions, or explanations before using them in an assignment or exam prep.

You no longer need to download a PDF and upload it if the title is in the catalog. The book stays available as a source you can query repeatedly.

How to add a free textbook

Open Gemini Notebook at notebook.google.com and sign in with your Google account. Create a new notebook or open an existing one you can edit.

Select Add sources in the left panel. Choose Textbooks from the options. The catalog opens with search and filters for topic, level, and country.

Search by title or browse. Select a book such as an OpenStax Calculus volume. Confirm the addition. The textbook appears in your sources list and counts toward your source limit (up to 50 on the free tier).

From that point, questions in the chat panel draw only from the selected sources, including the textbook. Inline citations appear in answers. Click one to jump to the relevant section.

The feature works on web and in the Gemini Notebook mobile apps. Availability follows your account region and the catalog coverage for the US and India.

Study with the added textbook

Once the book is a source, use the Studio panel on the right to transform it. Generate a study guide focused on chapters 1-3, create practice quizzes at different difficulty levels, or build flashcards for key terms.

Ask specific questions: “Explain the chain rule from this textbook with the exact example used.” The response cites the page or section. Follow up to request a summary or a comparison of two concepts from the same book.

You can combine the textbook with other sources, such as lecture notes or a YouTube lecture transcript, then ask questions that draw from multiple materials while still citing each one.

Tips for better results

Filter the catalog by country and level to match your course. OpenStax titles are common for US college subjects; S Chand covers many Indian curriculum books.

Turn off unused sources when you ask a focused question. This keeps answers tighter and citations clearer.

Hover over or click citations before you reuse an answer in notes or assignments. The tool grounds responses in the source, but always confirm important facts.

Pair this with other Gemini Notebook study tools. Create an interactive learning overview or a short video overview from the textbook content. See our guide on creating study overviews in Gemini Notebook for more options.

Limits and what to expect

The free textbook catalog is separate from the Google Play Books ebooks you already own. Those continue to work through the existing Expert Intelligence path. Textbooks from the new catalog do not require a purchase.

Source limits still apply. A full textbook counts as one source. Free accounts support up to 50 sources per notebook; higher tiers allow more.

Answers stay within the added sources. If a detail is missing from the textbook, the tool will not invent it from the open web.

Conclusion

Adding free textbooks turns Gemini Notebook into a course-specific study space. You get grounded answers with citations, plus tools to convert dense chapters into quizzes and guides. Start with Add sources, select Textbooks, and pick a title that matches your current class.

The feature rolled out October 29, 2026. Check the catalog in your notebook for the latest titles from OpenStax, Open Textbook Library, and S Chand Publishing.
