Scholarly? Professional? Popular?
When you have a research assignment, be sure to figure out what types of article sources are required or allowed. Some professors require you to use only scholarly peer-reviewed journals while others might let you use a variety of journals.
Scholarly article: Also known as peer-reviewed, academic, or refereed, these articles are written for researchers and experts and usually share the results of a research study. Scholarly articles are written by experts in the field and are reviewed by expert peers. In many databases, you can limit your search to scholarly, peer-reviewed, or refereed journals to weed out any non-scholarly content. Scholarly article example
Professional/trade article: Written for people working in a specific field. Articles can be written by experts in the field or by staff writers. The articles are only reviewed by journal editors, so they go through a less rigorous review process. Trade article example
Popular journals: Written for a general audience rather than for professionals or scholars, and written by journalists. Examples include The New Yorker, People, and Rolling Stone. Popular article example
Types of Articles
There are many different types of articles. The chart below can help you figure out which type(s) you're looking for or identify an article you've already found:
|News articles provide the most current information. Certain newspapers, such as the Wall Street Journal and the New York Times, are also known for thoughtful, in-depth analyses of important topics and events.|
|Popular magazine articles can help you generate ideas about issues, controversies, or unanswered questions about a topic, which you might want to explore further. They sometimes refer to studies or scholarly work that you can track down for more information.|
|Trade publications are written by and for professionals within an industry. These are an excellent source of very specific information from inside the field.|
|Scholarly journal articles go through a process of peer review before they are published. They are written by experts in the field (the people with letters after their name!) and their purpose is to advance the ongoing body of work within the discipline. These articles might present original research data and findings, or take a position on a key question within the field. They can be difficult to read, because their intended audience is other experts and academics, but they are at the top of the line when it comes to authoritative information.|

Evaluating Sources: Questions to Ask
How do you know if a source is right for your research? Below are some questions you can ask about your sources. There are no good or bad sources, but sources can be useful or not useful based on the evidence you're looking for.
- Who is the author? What do you know about the author’s background? (hint: Google the author). What makes the author an expert on this particular topic (remember that experience and research are markers of expertise as well as education)?
- What journal, magazine, organization, or website published this information? Look for an "about" page on the publisher's website (or explore their website) and also Google the name of the publication/organization/website (or look for a Wikipedia page about it) to learn more about the publisher of the information. What kind of reputation does it have? What is their purpose in sharing this information? Is it known for promoting specific points of view?
Can you tell where the information in the article came from? Do they share any information from other sources or does it seem like they’re sharing their opinion? If they used other sources, do those sources seem worth trusting?
Based on your answers to these questions, would you trust this source? If not, could anything from this article still be useful? Often articles link to other useful resources or mention other authors and studies that could be helpful.
You may not get good answers from all of these questions, but still trust a source. For example, an opinion piece from a noted expert in a specific field could be a useful source, but chances are, they are not going to be citing sources. Information from the Centers for Disease Control website is trustworthy, but much of it doesn't have an author. You have to weigh each of these factors when making your decision.
