Google: How did you do that?

We use Google, we use it a lot. Our students and faculty use Google a lot. But often we librarians are able to find things on Google that our patrons seem unable to find. It isn't that we are Master Google Hackers, but we are more likely to know about and use some advanced Google techniques. My all time favorite technique is to Google just a particular website or domain. Suppose you want to look for pages that are only on a site maintained by the California State government. Just go to Google, type in the terms you are interested in and add site:ca.gov. Or suppose you just want to search  sites from educational institutions: that's right, just add site:.edu
