Data & official recordsfree
Community-uploaded datasets on nearly any topic. Import the dataset description and discussion pages for context; raw data files aren't notebook sources.
The value for a notebook is often less the raw data file, which NotebookLM can't ingest directly as a dataset, and more the description and discussion pages, where uploaders and other users flag data quality issues, collection methods, and known pitfalls. That context is worth importing even when the dataset itself lives elsewhere. Because anyone can upload a dataset, provenance and quality vary a lot from one listing to the next, so it's worth checking who uploaded it and what they say about the source before treating a Kaggle page as authoritative.
Import into Gemini Notebook
- 1Copy the link above (or a specific page from the site).
- 2In your notebook, click Add source → Website.
- 3Paste the link and confirm — several links can be pasted at once, one per line.
Gemini Notebook 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.
