How to find reliable sources

The quality of your writing depends on the quality of your sources. A good fact from a credible source strengthens your work; a half-true claim from an unreliable one undermines it. Evaluating sources is a core skill.

What makes a source reliable

Authority. Who made it? An expert, a recognised institution, a reputable publication, or a primary source? Check the author and their credentials.

Accuracy. Is it grounded in evidence, with citations and dates? Does it distinguish facts from opinion?

Objectivity. Does it present a balanced view, or is it trying to sell or persuade you? Watch for bias, agenda, and sponsored content.

Currency. Is it up to date? For fast-moving topics, a recent source matters. For established facts, older authoritative sources are fine.

Primary vs secondary. A primary source is the original (a study, a document, a witness). A secondary source discusses it (a news article, a textbook). Prefer primary where possible.

How to search effectively

Start with the specific question. What exactly do you need to know? Then choose search terms that target it.

Use reliable databases and sites. Academic databases, official reports, reputable news, and the source's own site. Skip vague blogs and SEO aggregators for facts.

Go to the origin. If a claim is made, find the primary source behind it. Do not rely on a secondary article's summary.

Check the source's own page for the fact. "Verify information against the source" — a fact quoted by one outlet may be wrong; check the primary.

Look for corroboration. If you can find the same fact in two or more independent, credible sources, you are safer.

How to evaluate quickly

Ask: Who wrote this? What are their credentials? Is this fact or opinion? When was it published? Who is behind the site? If you cannot answer these, be cautious. Check the "About" page, the author, and whether there are citations.

Common mistakes

Using the first search result. Relying on a source with no author or citations. Treating opinion as fact. Using outdated sources for current topics. Trusting a single source. Quoting a source without checking the original.

Practical tips

• Keep track of each source and what you used it for.
