Additional Search Results:
The Additional Search Results feature allows you to automatically search for results in additional databases which are connected to your library’s whilst you’re searching on Google and Google Scholar for any online material. Simply click “Library Search” within the sidebar of the Lean Library extension.
You can also pin the Additional Library Search pop-up. The pop-up will remain on the page whilst you search for content on Google or Google Scholar. This allows you to simultaneously see search results appear from your library-subscribed content and Google Scholar without having to input the query again.
