Hi! I would say when looking for resources to use in a research report the most important criteria is relevance and reliability length. I say this because if the relevance of the essay isn’t important than that’s waste of what you are writing about along with if you can’t rely on the information your information will be will incorrect thus providing incorrect information. I hope this helped, Goodluck :)
