ECO 111 List of online economic resources. Here are 3 online principles of economics text sources. I have listed them in my order of preference, but you might find any one of the three more useful. The last site, about.com, is more like a search engine than the other two sites so it might be useful when we are looking at a specific topic. I also have a link to Amos web on the course web site that might be of use to you. http://william-king.www.drexel.edu/top/prin/txt/EcoToC.html http://www.netmba.com/econ/ http://economics.about.com/od/microeconomics/a/micro_text.htm
