Evaluate your sources
Remember, when deciding which resources to use for your research, ask yourself the following questions:
Am I using the right type of resource? ie too many books could make your research quite general - have you used any journal articles? are you using too many websites?
Are your resources current? Depending on your subject area, you made need to use only the most up-to-date of literature.
Is what you're using reliable? ie if it was found on the internet: is it a reliable source? when was the website last updated?
