Critique on Citation Machines

My favorite citation machine to use is EasyBib. It's very easy to figure out how to work things. I also like how you can look up certain books and websites and it finds information for your citation. Citation Machine and SourceAid were not as easy to use. The process got a little confusing at times because there was no place to "search" for books and websites. Overall, I think that Citation Machines are very useful and we are lucky to be able to use them today in the modern world.
