Types of Sources - What's the Difference

Learn quick and easy criteria for differentiating between common source types often used for projects and research at the university.

Scholarly / Peer-reviewed

A scholarly journal article, sometimes called a research or peer-reviewed article, is written by scholars and experts in a particular subject field. Your professors are scholars in the discipline they teach.

An article is part of a collection of articles in a publication called a scholarly journal. Because these articles are written by experts for other experts, they contain technical and specialized vocabulary (jargon).

Peer Review Process

A scholar prepares an article and submits it to a journal. A review process, known as peer review, requires submitted articles to be reviewed by other scholarly peers (or equals) to determine if an article should be published. When it works properly, the peer review process should ensure that only high-quality articles are published in a journal.

Article Title

Article titles are usually descriptive, acting as a very short summary of the article's contents. In your search results, scan the titles to identify potential articles to use. More matching words usually indicate a match to your topic but not always.

Author

The author or authors are usually listed below the title. Their credentials (qualifications) and institutional affiliations (where they work) will be listed somewhere on the article. An author's credentials can help you determine whether an article is credible.

Abstract

An abstract is a summary of an article (usually under 250 words). It presents the authors' research question(s), an outline of their study or experiment, and their findings or conclusions. Read this first to determine relevance to your topic.

Introduction

An article's introduction provides background about the topic the authors explored, the research question(s), and the relevance or importance of those question(s).

Body (parts 1 and 2)

The core of the article content that provides context for the research question, explains how the authors approached the question, and what they found. The Body typically is divided into sections like Literature Review (highlights related research), Methods (details of the study or experiment), Results (explains the findings), and Discussion (explores the implications of the findings).

Conclusion

The conclusion restates and summarizes the authors' findings and suggestions for future research. TIP: read the conclusion before you read an entire article. The summary will help you decide if the article is relevant for your project.

References

When you're reading an article, you may notice the authors citing the work of others. Any works that are cited in the text of the article will be listed in the References section. You can use the References section to find the authors' sources and read more information on your topic.
