Applied Geophysics - Spring 2019

You must evaluate all sources that you find - yes, even those found on library shelves or within the library’s databases!  So, what do you need to look for?

· Relevancy of resource to your topic

· Currency – are you doing a historical study or do you want only the most recent information about your topic?

· Authority/credibility/reliability of authors/editors/publishers

o What are their credentials?

o Are they considered experts in the field?  Do other scholars cite their works?

· Accuracy / validity

o Do other sources say the same thing?

o What supporting evidence (e.g., references) is provided?

· Biases – may have an effect on the information presented

o Who is funding/sponsoring the study?

o What are the author/editor’s affiliations?  Political viewpoints?  Religious beliefs?

o Is there balanced coverage, where all aspects of the subject are discussed to the same level of detail?

o Is it just-the-facts being presented or an interpretation of the facts?

o Are assumptions or opinions being made without supporting evidence?

o What is the context in which the information was created?

· Purpose & intended audience – this affects how the information is presented

· Referrals – Further Reading suggestions or hyperlinks if it’s a Web site

TIP:  The general rule of thumb has been that .gov (and most .edu) Web sites are usually reliable; however, you should evaluate those just as you would the .org and .com sites!
