Google has added hundreds of textbooks to Gemini Notebook at no charge, giving students a way to ask questions about a book and generate study materials without first finding and uploading its file. Match the catalog title and edition to your course before treating a book as a substitute for the assigned text.
The October 29 announcement names providers in the US and India, including OpenStax, Open Textbook Library and S Chand Publishing. Google says answers include citations and links to the textbook, and students can generate study guides, practice quizzes and flashcards.
Add a book through the textbook catalog
Google describes this route: open a notebook, choose Add sources, then select Textbooks to browse the available collection. Select the relevant book as a source for that notebook. You can then ask about its content or create study materials.
For the broader source workflow, Google's computer help page directs users to a notebook they own, either an existing one or a new one. It also warns that the mobile app can have limitations. Use the browser instructions if the source controls on your phone differ.
The imported book becomes one source among those selected in the notebook. Choose the sources you want the answer to use; otherwise, a question about one textbook can draw on other selected material too. Naming the book and chapter gives a more specific question than asking about a whole subject.
Keep the original book available for diagrams
Google's import documentation lists Play Books and textbook sources as text-only. A biology figure, a worked diagram or a carefully arranged table may therefore need attention in the original publication rather than an assumption that the imported version preserves its full presentation.
Use a citation to open the supporting passage and compare it with the claim in the answer. A reference helps you inspect an explanation; it does not prove the explanation, calculation or generated quiz is correct. Google's general product guidance acknowledges that the tool can make mistakes.
For course preparation, check the author, edition, chapter coverage and assigned problems. An introductory book on the right subject may still organize material differently from the one your instructor uses. A free alternative helps only when it fits the work you need to do.
The books are also available outside an AI notebook
You do not need to use Google's AI tool to read the participating US open-textbook providers' own collections.
OpenStax says its digital textbooks are free online and as PDFs. Most can be read without an account, although some titles, including certain nursing books, require one. Its subjects include science, mathematics, business, computer science and social sciences. Optional print editions and additional course tools are separate choices.
The Open Textbook Library, supported by the Open Education Network, provides books licensed for free use and adaptation. Its own library is broader than Google's announced selection; do not assume that every title on a provider's website appears in Gemini Notebook.
| Route | Useful for | What to check |
|---|---|---|
| Provider's online book | Reading chapters and inspecting the original material | Assigned title, edition and access requirements |
| Provider's PDF | Keeping a downloadable copy where offered | Edition and any later corrections |
| Gemini Notebook textbook source | Asking source-based questions and generating study aids | Catalog inclusion, citations and account limits |
Download and reuse rights follow the book's license. Free reading does not erase the need to credit an author or meet any conditions when you redistribute or adapt the material.
Free access still has account and usage conditions
Google's help says you must sign in with a personal, work or school Google Account. Managed accounts need their administrator to enable access. Browser eligibility follows the applicable age rules; Workspace for Education has different arrangements, and some features are restricted for under-18 users.
The source-help page currently allows free users up to 50 sources per notebook. Separately, Google describes compute-based AI usage limits that depend on the prompt, model, feature and chat length. Quotas refresh every five hours until the weekly limit is reached. Settings > Usage shows the account's allowance. Free catalog access does not mean unlimited AI requests.
Paid Google Play ebooks are a separate route: Google's instructions require an eligible purchased title in the same account. The textbook expansion does not make every commercial ebook free. Before buying a course package, compare the required book with the provider's direct free version, then check whether your instructor also requires a separate homework or assessment service.
