You should always check with your instructors on how they define "reliable" sources.
The term "reliable" is often used to distinguish sources that provide a thorough discussion or argument based on strong evidence. Reliable sources come in all different types of formats such as journal articles, streaming videos, and even blogs! While you may want to start your search for reliable sources in One Search, which includes must of the PC Library databases, you still must be the critical evaluator of each source to check its reliability.
You can use the CRAAPP Detector to help you evaluate your sources. "Keeping It Real: How to Spot Fake News," a PC Library research guide, can also help you distinguish quality reliable sources from the spectrum of fake news available on the web.
