How Research Materials
are Organized

When we talk about research literature, we make a distinction between primary and secondary sources. 

  • Primary sources publish the details of research studies. Research journals are the main primary sources, although dissertations also fall into this category. 
  • Secondary sources publish integrative reviews of broad areas of research. Some journals specialize in such review articles. Other secondary sources include books and chapters in edited books. 

We will describe each of these sources of information in the next section.
