When writing research papers, the researcher needs to evaluate the sources. He needs to make decisions about what to search, where to search, and once the relevant material is found, has to check whether it is a valid. The researcher faces difficulties in assessing the credibility of information, and it is extremely time consuming. At times, it can be frustrating. There is a vast amount of information at your disposal, but you may not find exactly what you need.
