Boolean Operators are words or symbols used as conjunctions to combine or exclude keywords in a search. Using these operators, you are able to focus your search on the results that will be most helpful. Google also has a few additional operators that work to refine results.

Why set up Google Scholar Library Links?
When Google Scholar is linked to our library's resources, you have access to the articles that the library has already purchased. They are hyperlinked in your Google Scholar search results. Without linking, these articles are unavailable through Google Scholar. Library linking makes your life easier.
How do I set up Library Links?
Visit scholar.google.com, then click the three horizontal lines to find the "settings" button. Click "library links," then search for "Principia" in the search box. Next, make sure all the check boxes are checked, click "save," and you're done!
