We’re making it easier to keep your sources and insights current in NotebookLM will also strictly respect file deletions and permissions. If a user’s access to a Drive file is revoked, they will no longer be able to use that file as a source in their notebook. The source will appear in the sources list with a link to the source for the user to request access. Additionally, if a file is deleted from Drive, it will be removed from the notebook as well, ensuring your research environment stays organized and secure.Getting startedAdmins: There is no admin control for this feature.
