Here are a few websites with some helpful information about writing a literature review, as well as some books that the library has that will provide more in-depth information (though perhaps not so useful if you’re not currently on campus).
The CRAAP Test
- When it comes to health, you often need current, up-to-date information. Check the website for a copyright date, or 'last updated' date, often at the very bottom of the page.
- Try the links on the page. If many of them are 'broken', it's likely that the page has not been updated or maintained.
- Check that the information is relevant to your question. Choose your search terms carefully to retrieve the most relevant results.
- Who is the intended audience of the website? Is the information meant for health consumers (lay people) or health professionals?
- A good website will provide clear information as to the author/owner of the site and the source of the information. You should be able to find an 'About' link somewhere on the page.
- Legitimate sites often provide contact information.
- The web address can be a clue to authorship: .edu indicates an educational institution and .gov indicates a government website.
- The accuracy of the information can be difficult to determine, but some clues may be a warning sign. Trust your judgement and beware of sites that make health claims that you know to be false or that are debunked by another reliable, trustworthy source.
- Beware of biased or opinionated language.
- Steer clear of websites that are poorly written, full of grammatical errors and spelling mistakes, or lots of exclamation points.
- The purpose of a reliable health information website should be to teach or inform. The information should be objective and impartial.
- Beware of sites whose primary purpose seems to be selling products, entertaining, or sites that are strongly biased or opinionated.
