Secondary research refers to books, articles and other material that summarize or critique other researchers' original work. (We provide more detail on the differences between primary, secondary and tertiary sources in this section of our 'Researching the topic' tutorial.)
To find more about both primary and secondary researchmethods, check out our Sage Research Methods database. It contains books, articles and tutorials on the spectrum of research methods used in qualitative and quantitative research. It also contains material on how to secondary research in the form of literature reviews.
