This is perhaps the most important step in your process of finding relevant and useful information. What you do here will influence the quality of results you obtain from using search tools such as library catalogues, journal indexes, databases of research literature, and Web resources.
Defining your terms, and broadening, narrowing and refining your search is an iterative process. It is always a good exercise to brainstorm and write down synonyms representing the topic of your information search. The terms you use to describe your topic may not coincide with the terms assigned by the indexers who analyzed the content of your search tools, or with the words used by authors although their works may address ideas and concepts similar to those you have set out to research.
For example, let's say your research topic is "career counselling". If you opt to skip the brainstorming step and do a basic keyword search for "career counseling" in the University of Lethbridge Library catalogue, you will retrieve more than 55 titles.
If you search for "career counseling," however, as a subject heading search, you are told that the catalogue uses the subject heading "Vocational guidance" instead. Clicking the link to the subject heading Vocational guidance produces a list of subject headings linked to almost 300 titles about vocational or career counseling, representing a list of sources far greater than your original basic keyword search using the same search terms.
Here are some questions to guide your process of brainstorming and recording synonyms and concepts related to your search topic.
Let's use the sample search topic "career counselling" to brainstorm some additional terms that could be useful (keeping in mind that variant spellings and terminology may also be involved):
Broader terms: | careers |
---|---|
professions | |
vocations | |
schools | |
counselling | |
Related terms: | school counsellors |
school psychologists | |
educational counseling | |
guidance counseling | |
Narrower terms: | high school counselling |
elementary school counseling | |
vocational interests | |
vocational qualifications |
Refinement of your search is guided by what you find. Tips on how to broaden and narrow your search are covered in the section on Basic Searching in this tutorial. If you do not find much that is relevant, you may be using terms that do not happen to coincide with those used in your finding tools.
Starting with your own words for describing your search topic will sometimes retrieve at least a few items that look somewhat useful. If this is the case, the important next steps are to:
Sometimes the terminology used in the profession will differ over time and across different databases. Explore and experiment with different terms.
Choose a subject of your choice and using the ERIC
Thesaurus write down the list of the broader, narrower and
related terms as outlined there. This will not only give you
practice in the ERIC Thesaurus, but it will give you help in understanding the
importance of using appropriate controlled vocabulary (more about this in the next step) in the research
process.
When you have completed this, go to the University of Lethbridge Library catalogue and use one or two of the ERIC thesaurus terms you wrote down to search the Subject Heading index. Do your searches retrieve any results? Are the ERIC Thesaurus descriptors for your search topic the same as those used in the U of L Library catalogue?
