This is a knowledge-worker pro tip: custom search engines (CSE). The idea is that you collect a number of authoritative sites on a subject - Climate change, Indigenous news and resources, or Knowledge Management, say - and then set up a Google search only on those sites. " Check it out at https://cse.google.com/ and make your own," advises Marshall Kirkpatrick. Now that said, I don't use CSE at all. But then again, I have the rich resource of RSS to feed me all the knowledge I need (or can handle).
