Sources worth feeding NotebookLM

A notebook is only as good as what you put in it. Every entry below has a copy-ready link — paste it straight into NotebookLM's Add source dialog — plus a tip on the cleanest import route for that kind of material.

  1. 1Copy a link. Use the Copy link button on any source below.
  2. 2Open Add source. In your notebook: Add source → Website (or Link).
  3. 3Paste and confirm. You can paste several links at once — one per line.

Academic papers

NotebookLM reads the text of the page you give it. Paste pages that carry the full text (an arXiv abs page, a PubMed Central article) — a paywalled landing page imports as just an abstract.

  • Google Scholarscholar.google.comfree

    The widest net for finding papers across every field; follow its links to a full-text version before importing.

  • arXivarxiv.orgfree

    Preprints for AI, CS, math and physics. Paste the abs page URL as a Website source — figures survive that route better than an uploaded PDF.

  • Semantic Scholarsemanticscholar.orgfree

    AI-assisted paper discovery with citation graphs — good for building the reading list before you build the notebook.

  • PubMed Centralncbi.nlm.nih.gov/pmcfree

    Free full-text biomedical papers — unlike PubMed proper, articles here import complete, not as abstracts.

  • SSRNssrn.comfree

    Working papers in economics, law, finance and the social sciences, most downloadable as full-text PDFs.

Data & official records

NotebookLM is a reading tool, not a spreadsheet engine — feed it the written reports and summary pages, not raw CSVs, and ask about what the documents say.

  • World Bank Open Datadata.worldbank.orgfree

    Development and economic indicators for every country, each with a written overview page that imports cleanly.

  • Macroeconomic outlooks and country reports — the Article IV PDFs are dense, citable source material.

  • OECD Datadata.oecd.orgfree

    Comparative statistics and policy reports across member economies, with strong methodology notes.

  • SEC EDGARsec.govfree

    Every US public company filing — 10-Ks and 10-Qs make excellent grounded sources for company research.

  • Our World in Dataourworldindata.orgfree

    Long-form, sourced explainers on global trends — article pages import with their context intact.

Books & archives

For public-domain books, download the Plain Text file and upload it — the 500,000-words-per-source limit fits most novels whole. ePub uploads are supported too.

  • Project Gutenberggutenberg.orgfree

    75,000+ public-domain books. Grab the Plain Text UTF-8 edition for the cleanest import.

  • Internet Archivearchive.orgfree

    Books, historical documents, magazines and archived websites — much of it downloadable as text or PDF.

  • Standard Ebooksstandardebooks.orgfree

    Carefully typeset public-domain ePubs — a cleaner starting point than raw scans for literature notebooks.

  • Wikisourcewikisource.orgfree

    Transcribed historical texts, speeches and primary documents, page-linked and citable.

  • Open Libraryopenlibrary.orgfree

    Catalog and lending arm of the Internet Archive — useful for finding which editions exist and where.

Code & ML research

Documentation pages import better than repositories: paste a project's docs URL or README page, not the repo root.

  • Papers with Codepaperswithcode.comfree

    ML papers matched to their implementations and benchmarks — import the paper page and the README together.

  • Hugging Face Papershuggingface.cofree

    A daily-curated feed of AI research, each paper with a discussion page that adds context.

  • GitHubgithub.comfree

    READMEs, docs folders and wikis are strong sources for how a tool actually works — paste the rendered page URL.

  • MDN Web Docsdeveloper.mozilla.orgfree

    The reference for web platform APIs — reliable ground truth for a web-dev notebook.

  • Stack Exchangestackexchange.comfree

    Accepted answers on the technical sites make good targeted sources for narrow questions.

Courses & textbooks

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

  • MIT OpenCourseWareocw.mit.edufree

    Full courses with downloadable lecture notes and exams — the notes PDFs are ideal notebook sources.

  • OpenStaxopenstax.orgfree

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

  • Khan Academykhanacademy.orgfree

    Article-format lessons import directly; video lessons come in via their YouTube versions.

Video & audio

Public YouTube videos with captions import as sources directly, with timestamped citations. For podcasts, upload the audio file — NotebookLM transcribes it.

  • YouTubeyoutube.comfree

    Lectures, talks and interviews — paste the video URL. For whole channels or playlists, see the tools page.

  • TEDted.comfree

    Every talk has a full transcript page — paste that URL for a cleaner import than the video.

  • Podcast episodespodcastindex.orgfree

    Find the episode, download the audio file, upload it as a source — long interviews become quotable, searchable text.
