Readers of this blog may be interested in a piece I wrote for the Scientific American Guest Blog, How to: Track down journal articles cited in news stories (when they don’t link directly).
Many blog posts will link directly to a version of the original article, but many news sources often have a policy of not linking to the original source. Even when a blog links directly to the original article, you may not be able to read the it without paying. But there are steps you can take to find the original article, and to find a version of it you can read.
