NotebookLM removes sources one at a time from each source menu. With NotebookLM Ultra Exporter, tick the sources in the Sources panel and choose delete selected sources from the tools menu to remove them together. Deleting cannot be undone, so download or archive them first.

## What to know

- Deleting a source also removes it from the grounding of future answers.
- Existing notes stay, but their citations to that source no longer open.
- To free slots without losing content, merge sources instead.

> Google changes these menus often. The item's own menu in your notebook shows what is built in today.

## Frequently asked questions

### Can I recover a deleted source?

No. Re-add it from the original link or file, or restore it from an archive.
