The encyclopedia-a most underrated resource!

Every now and then I like to do a random search for something I know nothing about. (Okay, I actually do this often.) It keeps me on my toes. Today I felt like finding out about strange encyclopedias. I regularly use WorldCat so that seemed like a logical place to go to get a a million and one results. As I'm doing this, I realize I want reviews of encyclopedias. So off to another resource!

I also did some looking on Booklist Online. (Note: to get the long view of the reviews you do have to be a subscriber. However, some of the titles feature "buy it on Amazon" links. You can go use these to hop on Amazon to see reviews listed there too. Some come directly from Booklist.)
