As you retrieve sources, skim the article to get the “big picture” to ascertain its relevancy to your topic. You don’t have to understand every single idea in a text the first time you read it.
DON'T FORGET TO SAVE RETRIEVED SOURCES!
Where was the paper published? What kind of journal it is? Is the journal peer-reviewed? Can you tell what the paper is about? Who are the authors? What are their credentials? Where are they from? What are the sections of the article? Are these clearly defined?
What is the overall context? Is the problem clearly stated? What does the paper bring new? Did it miss any previous major studies? Identify all the author’s assumptions.
