For a literature review, load the candidate papers into one notebook, ask NotebookLM for a comparison table by theme, method and finding, then draft section by section from cited notes. NotebookLM Ultra Exporter handles bulk import by DOI and exports the table to Excel, the notes to Word and the references to BibTeX or RIS.

- When the notebook is full, [merge sources into one](https://nlmexporter.com/guides/import/merge-sources-to-notebooklm) to free slots.

## 2. Work in NotebookLM

- Ask for themes, then for the papers that support and contradict each theme.
- Use the [literature review outline prompt](https://nlmexporter.com/guides/prompts/literature-review-outline-prompt).

## 3. Get the result out

> A notebook only knows the papers you loaded. It cannot tell you what the field says, only what this set says.

## Frequently asked questions

### How many papers fit in one notebook?

Google documents 50 sources per notebook on the free tier and more on paid Google plans. For a larger corpus, split by theme or merge related sources.

### Can NotebookLM answers be trusted for this?

NotebookLM answers from the sources you give it and cites passages, which makes checking fast, but it can still misread a source. Open the cited passage for anything you will reuse, and keep the export as your record of what was checked.
