It is important to know that the Web is an unregulated resource. Because many unreliable sources exist on the internet, anyone – even people who have no expertise at all in your subject – can post anything at anytime. Many sources on the web have proven to be unreliable, biased, and inaccurate. Too much reliance on the web could do more damage than good. Checking the reliability and accuracy of information taken from random sites could take more time than going to the library. And using information you have not checked from such sources could have a detrimental impact on your final grade.
