One thing that I am still confused about is how to find a good secondary source for a paper. I often use Google to search for related topics, but I find that many of the results are not approved academic sources. For example, many professors suggest using Galileo to find a scholarly article, or book but I find this program to be very confusing. Every time I have used it, it gave me articles that were either off topic or ridiculously long. How do I use resources in the library to find approved sources for my papers?
