Is the information covered fact, opinion, or propaganda? Here, you must discern fact from opinion.
Facts can usually be systematically verified; opinions, though they may be based on factual information, evolve from the interpretation
of facts.
Are
there any errors or omissions. Are there any assertions not supported by factual information?
Is the author's point of view objective and
impartial? Look for emotion-arousing words that may signal bias.
Is the material primary or secondary in nature? Primary sources (interviews,
etc.) are the raw material of the research process. Secondary sources (Books, encyclopedia articles, and scholarly journal
articles) are based on primary sources.
