Enter "simple Wikipedia." Type in something you want to look up, such as Einstein and then "simple wikipedia" and you will get back a one page summary that even begins with a one hundred word mini summary and then provides links and summaries on the side. So if you need more depth, you can go find it elsewhere. But if you are looking for some quick details, it is better than Wikipedia.
What I love the most about this is that I found out about it from my daughter Madison. Isn't that the way it should work. Teachers teach and then learn from their students in a symbiotic relationship.
