Who is the person – or organization -- responsible for compiling and presenting the information?
Check to see if there is information available on the author/s.
Do they have any special experience or degrees that might make them a more reliable source than someone else? If you cannot find an individual author (or editor, or artist or director) is there a sponsoring organization that might be considered reliable?
If you know them to be acknowledged experts in the subject area covered then there is good chance the research work will be of high standard (though it would be dangerous to assume this without further critical review of the paper!) when was the text produced?
Does the author state the goals for this publication?
Inform, explain, educate ,Advocate ,or Sell a product or service
Is the information covered fact, opinion, or propaganda? It is not always easy to separate fact from opinion. Facts can usually be verified; opinions, though they may be based on factual information, evolve from the interpretation of facts. Skilled writers can make you think their interpretations are facts.
Does the author exhibit a particular bias?
Commitment to a point of view
Does the information appear to be valid and well-researched, or is it questionable and unsupported by evidence? Assumptions should be reasonable.
Fact : Facts can be all or some of the following: can be proven, real for all people and places, can be duplicated, can be observed, historical, or 100 percent true, but fact can also be changed e.g., of 20 million populations in Malaysia in 2000, but after 5 years it is change.
