I designed this research guide to help you find topics for your research paper about gas drilling, and to help you find good resources for the information you'll need to write the paper. There are several ways to make sure that you find research-quality information.
It can be a good choice to go to locations where you know you'll find good resources. If you use the library databases to find articles about your topic, you can specify that you'll only accept "scholarly" or "peer-reviewed" articles, and what you get will come from sources which have been written or at least edited by experts in the field. Even if you don't make that specification, though, you will get articles that have been published in legitimate publications by authors whose identities and credentials you can verify.
If you choose to look for websites, there are tools which can help you find out whether you can trust the information you find, or you can work from lists of websites that have already been evaluated as good choices.
Either way, you're sure to find a wide variety of material about this often controversial topic!
