Source types make up the scope of the literature you are searching. Common source types include:
What are "peer-reviewed" journals?
A peer-reviewed journal is a respected academic publication. Before articles are published within these types of journals, they are sent by the editors of the journal to other scholars in the field ("peers"), often anonymously, to get feedback on the quality of the scholarship, review research methods, as well as relevance or importance to the field. The article may be accepted, often with revisions suggested, or rejected for publication.
Peer-reviewed journals are highly respected, and researchers wish to have their works published in them. Many often have low acceptance rates.
One way to find peer reviewed articles is to type your keywords into Summon, and then choose the filters for Scholarly & Peer-Reviewed and Journal Article. You can also search our Databases (organized by subject) for peer-reviewed articles.
The Important Questions of Evaluation: Digging Into Your Sources (3 Levels)
| The 5 Ws (and one H) | The Surface-Level Questions | The Deeper Questions |
|
Who? |
Who is the author, editor, or creator? Is the author qualified to write about this topic? |
What makes them qualified? First-hand experience? An advanced degree? |
|
What? |
What type of document is it? For example, is it a newspaper article? A blog? A government website? A scholarly article? A book? What is it about? |
Some sources have gone through a more rigorous review process than others. Is the source appropriate for the type of research you are doing? |
|
When? |
When was this source published? Is the information up-to-date? |
The 'up-to-date'-ness of a source matters more for some research questions than others. |
|
Where? |
Where did you find the source? A library database? A website? For websites, what is the URL ending? For example, .com? .gov? .org? .edu? |
There is no 'bad' type of source, but sometimes source types can give you a better idea of where to find certain types of content. |
|
Why? |
What was the goal of the author or publisher? Is there bias? |
Are those biases disclosed? Do they impact the quality of the information? |
|
How? |
How did the author(s) gather data and information? Did they include citations? Did they derive reasonable conclusions from the research? |
What types of sources did the authors cite? Was their work reviewed by anyone else? |
Many of these questions will NOT (a) be easy to find answers to and (b) tell you that the source you are reading is 100% credible, but they are still important to ask. Digging into a source itself and finding out more about it is part of the research process.
Evaluating sources is an ongoing activity you will do throughout your research, and it includes evaluation of your own search process.
As you search, pay attention to the keywords and phrases you are using. Are you looking for information that will only confirm what you already suspect, or are you looking for possibly contradictory or opposing information as well? Do you have any 'go-to' sources that you use to find information? Are you looking in too narrow or too broad an area for information?
