Types of Information Sources
Source types make up the scope of the literature you are searching. Common source types (which can be in print or online) include:
Please see the chart below for further discussion of resource types and the kinds of information each resource conveys. As students begin to approach the research process, they should ask themselves what kinds of informational needs they may have for their projects or course assignments, as well as how different types of resources address some of these needs.
Questions to Ask When Evaluating the Sources You Find:
| The 5 Ws | 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? |
Is the source type appropriate for the type of research you are doing? Is it relevant to your research? |
|
When? |
When was this source published? |
Is the publication date appropriate for the type of research you are doing? |
|
Where? |
Where did the authors get their information from? Are citations provided? |
Did the authors cite sources that are credible? |
|
Why? |
What was the goal of the author or publisher? Who is the intended audience? |
Is there bias? Bias does not necessarily negate credibility. We all have biases. The question then becomes: are those biases disclosed? Do they impact the quality of the information? Was this source created for a scholarly audience or a more general audience? |
Do your best to find the answers to these questions. Use these questions to help answer the broader question: Is this source appropriate to use for the research that I am conducting?
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? Or are you using a variety of search tools and looking for different points of view?
Keywords & Subject Headings: When looking for resources in the Gordon Library catalog, a good initial strategy to guide your search is using subject headings as your keywords. Subject headings are preferred, standardized terms developed by subject area experts, whereas 'keywords' are generally based upon natural or subjective language. In this way, Subject Headings are a kind of controlled vocabulary, and they form the organizational backbone of searchable platforms, which facilitate automated, efficient searching. Many libraries (WPI included) use Library of Congress Subject Headings (LCSH)--which are generated by the Library of Congress--as their preferred terms. As it relates to searching, the key difference is that Keyword searches look at most (if not all) of the words in a catalog record, but subject searches only look for words in the subject heading fields (6XX). As a result, subject searches are more precise, so subject search results will be more specific. Consider some of the approaches recommended by librarians in the following video--
