Is it Scholarly?
How can you tell if something is scholarly?
Is the author an academic?
Are they employed at a university? Do they have a Ph.D.? If the source doesn't say, use Google.
Are there lots of footnotes, endnotes, or references?
Is it published by an academic press? (for books)
Often these contain the name of a university [Oxford University Press}, if not, use Google to find the press and read about their editorial board/policies.
Is it published in a scholarly journal? (for articles)
Sometimes these contain the word "journal" in the title, if not use Google to check out the journal's website & editorial board.
If the answers are yes, you probably have a scholarly source--it's gone through a rigorous peer review process. If you are unsure, ask your professor or a librarian!
