For my analysis I chose this story from Nicar.org. The author is simply "Extra Extra," and the article looks into chemical safety board investigations.
The main record used by the writer came from the Center for Public Integrity. The article is about how the U.S. Chemical Safety Board is operated sluggishly and how the things that are required to be done, say, annually, are usually put off. According to the article, the number of safety bulletins, accident reports, and case studies has fallen since 2006.
The writer had to actively look for the report because this isn't the kind of thing that press releases are sent out for. The reporter probably had to have the database where this came from in his arsenal or he never would have known about it. This is certainly not the kind of thing that is "common knowledge."
Since the data came from the Center for Public Integrity, the reporter had to probably do a lot of research and use different databases to find that particular report. He found his thing in the world by probably asking around and finding a good website to find the information on.
