Answer:
Timeliness
Your resources need to be recent enough for your topic. If your paper is on a topic like cancer research, you would want the most recent information, but a topic such as World War II could use information written in a broader time range.
Authority
Does the information come from an author or organization that has authority to speak on your topic? Has the information been peer-reviewed? (You can use Ulrichsweb to determine if a journal is peer-reviewed). Do they cite their credentials? Be sure there is sufficient documentation to help you determine whether the publication is reliable including footnotes, bibliographies, credits, or quotations.
Audience
Who are the intended readers and what is the publication's purpose? There is a difference between a magazine written for the general public and a journal written for professors and experts in the field.
Relevance
Does this article relate to your topic? What connection can be made between the information that is presented and your thesis? An easy way to check for relevance is by reviewing the Abstract or Summary of the article before downloading the entire article.
Perspective
Biased sources can be helpful in creating and developing an argument, but make sure you find sources to help you understand the other side as well. Extremely biased sources will often misrepresent information and that can be ineffective to use in your paper.
Websites create an interesting challenge in evaluating credibility and usefulness because no two websites are created the same way. The TAARP method described above can be used, but there are additional things you want to consider when looking at a website:
The look and feel of the website - Reliable websites usually have a more professional look and feel than personal Web sites.
Informational Resources are those which present factual information. These are usually sponsored by educational institutions or governmental agencies.
Advocacy Resources are those sponsored by an organization that is trying to sell ideas or influence public opinion. (These resources may include
Business or Marketing Resources are those sponsored by a commercial entity that is trying to sell products. These pages are often very biased, but can provide useful information. (
News Resources are those which provide extremely current information on hot topics. Most of the time news sources are not as credible as academic journals, and newspapers range in credibility from paper to paper.
These sources can be helpful to determine what people are saying on a topic and what discussions are taking place. Exercise great caution if trying to incorporate these sources directly into an academic paper. Very rarely, if ever, will they hold any weight in the scholarly community.
Are there advertisements on the site? - Advertisements can indicate that the information may be less reliable
Check the links on the page - Broken or incorrect links can mean that no one is taking care of the site and that other information on it may be out-of-date or unreliable.
Check when the page was last updated - Dates when pages were last updated are valuable clues to its currency and accuracy
