Literature: Search & Evaluation Strategies

Research Strategies

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.
  • 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.
  • 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).
    • Subject searches are more precise, so subject search results will be more specific.

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? 

Who is the publisher?

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?

There is no 'bad' type of document, but some have gone through a more rigorous review process than others.
When?

When was this source published?

Is the publication date appropriate for your research? 

The 'up-to-date'-ness of a source matters more for some research questions than others. 
Where?

Where did you find the source? In a peer-reviewed journal? In a library database? On a website?

For websites, what is the URL ending? For example, .com? .gov? .org? .edu? 

Be strategic about where you look for information. Which search tool, database, or website is most likely to have the kind of information you need?
Why? What was the goal of the author or publisher? 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?

How?

How did the author(s) gather data and information? Did they include citations?

Did they derive reasonable conclusions from the research?

Did the author(s) only cite themselves/their associates?

How well did they explain their process?

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? 

 

Other Helpful Source Evaluation Guides/Documents: 

Peer-Review Definition

Peer-review: "A process by which a scholarly work (such as a paper or a research proposal) is checked by a group of experts in the same field to make sure it meets the necessary standards before it is published or accepted."

  - Merriam Webster, https://www.merriam-webster.com/dictionary/peer%20review 

 

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 WPI Library Search, and then choose the filter for Peer-reviewed Journals. You can also search our Databases (organized by subject) for peer-reviewed articles.

 
Use these search terms, known as Boolean operators, to narrow or broaden your search:
Term Example  Result
AND
media AND bias
Narrows the search to entries containing both terms.
OR
beer OR wine
Broadens the search to entries containing either term.
NOT
bat NOT baseball
Excludes entries containing the second term.
" "
“social work”
Retrieves results containing the exact phrase in quotes.
?
globali?ation
Wildcard: Retrieves both globalization and globalisation.
*
doctor*
Truncation: Retrieves doctor, doctors, doctored.

What or Who is Boolean?

Boolean operators are named for George Boole (1815-1864), who was a mathematician, logician and philosopher whose legacy of Boolean algebra and symbolic logic is credited with laying the foundations for the information age.

  1. Ask a librarian: Searching and researching is what we do. Let us work with you to make your searching more productive.

  2. Use search filters on the search results page. Some of the most common filters are:

    1. Date
    2. Source Format – book, journal, video
    3. Source Type – Academic Journals, Magazines, Newspapers
    4. Subject – Keywords and phrases found prominently in your search results. Add these as additional search terms.
  3. Identify your topic’s key concepts and their synonyms: Add synonyms for your keywords and concepts to increase the number of relevant search results.

  4. Use the FullTextFinder icon on the search results page. If you only have the summary/abstract of an article, click on the FullTextFinder to search all 200+ library databases for the full-text.

  5. Use Interlibrary Loan (ILL). Submit an ILL request to get full-text journal articles, books and book chapters.

  6. Check bibliographies for additional relevant sources.

  7. Check “cited by” links on search results page.

  8. Check “related articles” links on search results page.

  9. Use Google search features to focus on domain type (e.g. .edu, .gov, .org,) or country ( e.g. .au, .nz)

           Examples:

  • Community garden site:.gov
  • Fauna site:.nz
