When doing your research, it is important to follow the information back to the original source. The first source/author we read does not necessarily = the “original” source of information.
For example, if you are reading an article by Taylor, and in the article Taylor makes a reference to a study done by Jones, it is necessary to track down Jones' study. Then, you can look at Jones' research yourself and make sure it is credible, reliable, and that Taylor has accurately interpreted Jones' work. Continue following the citations back to the original source of information.
Taylor cites Jones-->Jones cites Krugman-->Krugman cites a study by the Environmental Protection Agency
Here is another example. If you are reading an article in a newspaper, pay careful attention to where the reporter is getting her information. How does she know solar energy is gaining popularity in the United States? Is she referring to a report, a journal article, a website? If you use that newspaper article in your research, you must find and cite the original report or article.
Why is this so important?
First, by reading the full text of the original source, you can verify that the context of the quote supports the point you want to make.
Second, by finding and reading the original source, you will become better informed about your research topic.
