How to Cite NotebookLM in APA, MLA, Chicago or BibTeX

The first time I tried to write a literature review with NotebookLM, I hit a wall that had nothing to do with the AI being smart. It was smart. The problem was getting anything out of it in a shape my reference manager would accept.

NotebookLM (Google renamed it Gemini Notebook in July 2026 — same app, same notebooks) is genuinely good at pointing you back to the source. You ask a question, you get an answer, and every claim has a little numbered chip you can click to land on the exact sentence in the PDF. For reading, that's great. For citing, it's useless — because a highlighted sentence in a 40-page PDF is not a citation. There's no author string, no year, no page number you can paste after a quote. You still have to build the reference yourself.

So here's the manual workflow I settled on, and then the shortcut I use now that I don't have the patience for the manual one anymore. (Citations are just one of NotebookLM's export limitations; this guide is the deep dive on the citation part.)

A NotebookLM citation is not an APA reference

Treat the citation chip as evidence navigation, not as the finished bibliography entry. It helps you verify the passage; the reference still needs the source metadata and the rules of the style you use.

The manual way (works, but it's fiddly)

Say NotebookLM gives me a claim backed by citation [4]. Here's what I do, in order:

1. Click the citation chip. It jumps to the passage inside the source viewer.
2. Open the source itself and find the metadata — title, author(s), year, publisher or journal, and a URL or DOI. For an uploaded PDF this is usually on the first page or in the file properties; for a website source it's in the page itself.
3. Decide the format. If I'm writing in LaTeX or keeping things in Zotero, I want BibTeX. If it's a Word doc for a class, I want a ready-made APA or MLA string.
4. Type it out. A BibTeX entry ends up looking like this:

@article{smith2021attention,
  author  = {Smith, Jane and Doe, Alan},
  title   = {Attention and Memory in Adult Learning},
  journal = {Journal of Cognitive Science},
  year    = {2021},
  volume  = {14},
  pages   = {231--248},
  doi     = {10.1234/jcs.2021.0042}
}

…and the same source in APA 7th looks like this:

Smith, J., & Doe, A. (2021). Attention and memory in adult learning. Journal of Cognitive Science, 14, 231–248. https://doi.org/10.1234/jcs.2021.0042

Do that once and it's five minutes. Do it for thirty sources across four notebooks the night before a deadline and you'll understand why I stopped.

Where it actually goes wrong

Two things trip people up. First, uploaded PDFs often have messy or missing metadata — a preprint might not list the year cleanly, and NotebookLM won't invent it for you. You have to go check the original. Second, once you have a dozen notebooks going, you lose track of which source lived where, so half the time is just finding the thing again.

The one-click way

This is the part I built NotebookBloom for, because it was my own daily annoyance. Instead of copying fields around, it reads the source details already sitting in your notebook and generates the reference for you — APA, MLA, Chicago, or BibTeX — ready to paste.

• Pick the source (or a batch of them).
• Choose the style. BibTeX drops straight into a Zotero or Mendeley library as a .bib file; APA/MLA/Chicago come out as formatted strings.
• Copy, paste, done. The reference carries the source link so you can always trace it back.

Does this still work now that it's called Gemini Notebook?

Yes. The rename from NotebookLM to Gemini Notebook was cosmetic — same site (notebooklm.google.com), same notebooks, same citation chips. Everything above works whether the tab says NotebookLM or Gemini Notebook. If you learned this workflow before the rename, nothing changed except the logo.

If you write anything that needs a bibliography, sort this out once. Future-you, at 1 a.m. before a submission, will be grateful.
