English -- ENG 110,120,122: Evaluating Resources
On this page you will find some brief guidelines to use when analyzing a web site and determining its value for your research. You might not be able to answer all the questions about a certain web site. If you find that there are a LOT of questions you can't answer, or if the answers you get aren't satisfactory, you probably shouldn't use that web site as an information source.
Evaluate Using the CARDS Method
Regardless of the type of resource you are examining, always evaluate the accuracy and reliability of the information you find before using it for your research. Use the acronym CARDS to help you do that evaluating. Consider the following questions when determining the quality of an article or source:
C - Credibility:
- Is the author, publisher, or sponsor of the information evident? What are their credentials, reputation, education or affiliations?
- Is there an "About Us" or "Contact Us" link? Besides an email address, is there a phone number or postal address to contact for more information?
- If it's a book or article, is the author reputable? Does the reference have a bibliography?Is the information still valid today?
A - Accuracy:
- Do you see errors on the page (spelling, grammar, facts)? Errors like these not only indicate a lack of quality control, but can actually produce inaccuracies in information.
- Do they cite the sources of their information?
- Is the source objective or does it advocate a certain point of view? Use objective sources first, but consider using those advocating different points of view as well.
- Is the information free of advertising or clearly separated from it?
D - Date:
- Can you find the copyright date?
- Are there dates for when it was written or when it was last revised?
- Do any statistics, graphs, or charts clearly state when the data was collected?
- Are there links which no longer work?
- Is the information based on primary or secondary sources?
- Are there links to other sources that would score high in this C.A.R.D.S. evaluation?
