Although textbooks may go through a peer review and editing process, it is still important for you to take a critical look at the information you find in a textbook. Here are some criteria to consider applying to websites.

• Authority – what are the qualifications of the authors and/or editors?

• Accuracy – is the information reproducible or cited by other sources? Are references cited throughout the book?

• Bias – does the author or editor have a conflict of interest?

• Currency – when was the book published? Are there newer editions? Is the information out of date for your purposes? 

• Comprehension – is the information written at an appropriate level for its audience? How does the information compare with other sources on this topic? Is the textbook well organized and easy to follow?

The ABC's of evaluating websites

There is no quality control or peer review on the Internet. Therefore, it is important that Internet users are able to critically appraise the quality of the information they come across. Here are some criteria to consider applying to websites. 

• Authority – can you identify who wrote the information, and is that person or organization a reputable resource? 

• Accuracy – is the information reproducible or cited by other sources?

• Bias – are there conflicts of interest, i.e. is the company selling a product or do the website organizers have a specific agenda? Are the goals or aims of the website clearly stated?

• Currency – when was the webpage last updated? Are the links up-to-date?

• Comprehension – is the information written at an appropriate level for its audience? How does the information compare with other sources on this topic?
