Not Every Website Is a Good Source — Here's How to Tell the Difference
When you're working on a research project, finding information online is easy. Finding reliable information is the real skill. Before you copy that URL into your bibliography, use this guide to make sure your source is trustworthy, accurate, and appropriate for school work.
The CRAAP Test: Your Research Checklist
Librarians and researchers use a simple framework called the CRAAP Test to evaluate any source. It stands for:
- Currency — When was the information published or last updated? For science or current events, recent sources matter. For history, older primary sources may be valuable.
- Relevance — Does the information actually answer your research question? Is it written for an audience like you — a student — or is it too advanced or too basic?
- Authority — Who wrote it? Look for an author name and credentials. Is the site run by a school, government agency, or recognized organization?
- Accuracy — Are facts supported by evidence? Does the article link to or cite other reliable sources? Can you verify the information elsewhere?
- Purpose — Why was this written? Is it meant to inform, persuade, sell, or entertain? Understanding the purpose helps you spot bias.
Reliable vs. Unreliable: A Quick Comparison
| Reliable Sources | Use With Caution | Avoid for Research |
|---|---|---|
| .gov and .edu websites | Wikipedia (use for background only) | Anonymous blogs |
| Library databases (EBSCO, JSTOR) | News websites (check for bias) | Social media posts |
| Peer-reviewed journals | Encyclopedias (great starting point) | Sites selling products |
| Published books & textbooks | YouTube (academic channels only) | Sites with no author listed |
Pro Tips for Smarter Searching
- Start with the library databases. Resources like EBSCO, Britannica School, and PebbleGo are already vetted — everything in them has been reviewed for quality.
- Use Google Scholar for academic papers. Add site:.edu or site:.gov to your Google search to filter for institutional sources.
- Read "About Us" pages. Legitimate organizations are transparent about who they are and what they do.
- Cross-check facts. If you find a surprising statistic, look for at least two other reliable sources that confirm it.
- Ask a librarian! That's what we're here for — stop by or send an email anytime.
A Note on Wikipedia
Wikipedia is a great place to start your research and get a general overview of a topic. However, because anyone can edit it, it is not appropriate to cite directly in a school paper. Instead, scroll to the bottom of any Wikipedia article and check the References section — those linked sources are often exactly what you need.
Bottom Line
Evaluating sources is a skill that takes practice, but it becomes second nature quickly. When in doubt, ask yourself: Would I trust this information enough to stake my grade on it? If not, keep looking. The library is always here to help you find sources you can count on.
