For example, I am adamant that students should avoid citing Wikipedia in their research writing.
I am also unapologetically opposed to quotation websites where students have been known to cut and paste quotations from great thinkers such as Aristotle or Plato.
Here’s an infographic to help you make wise choices about what kind of material to include in your literature review.
If your topic has limited sources available in the research, find and analyze what you can, but avoid “padding” your literature review with non-scholarly sources.
It is not that these sources are not credible, but that you want your research literature review to be strongly focused on research materials.
For that reason, I recommend that not more than 5% of sources come from this category.Regardless of whether it is part of a project or a standalone work, we (your professors) expect certain kinds of sources.We learned what kinds of sources to include in literature reviews when we were students, but we are not always so good at articulating what those expectations are.In my view, quotations for research writing ought to come from original works (or in a pinch, a translation of an ancient text).Your professors or research supervisors will have their own ideas about what kind of sources to include in your literature review, so be sure to consult with them.The quantity of sources you consult may be important, but quality is definitely important.Talk with your supervisor about their expectations and get guidance as you go along.The result can be frustration for both students and professors.In this post, I have curated tips and information that I have been sharing with graduate students over the past several years.When you are learning how to write a literature review, it can be tricky to figure out what kinds of sources to include.Remember, you want to focus on producing a review that is evidence-informed and research-based.
