Where is the best place to find academic / scientific sources for professional studies?

I am currently working on a research study and am trying to find other academic works related to my topic, which is actually regarding the Reddit community. Can anyone help guide me to some helpful places where I might find research or written works that were produced by professionals or are considered scholarly?
