Scholarly Sources

Now you have developed some understanding of your topic and have formulated your research question. It's time to find more scholarly materials to develop and support your arguments in the essay.

Scholarly sources help you develop an academic argument for your research. Scholarly journals and books are two major scholarly sources you will need for your research work.

You have probably heard from your instructor that you would need to read peer-reviewed journal articles. So what are peer-reviewed journal articles and where to find them?

Find Peer-Reviewed Journal Articles

What are Journal Articles?
What are Peer-reviewed Journals?
  • Present the findings of a study, research or experiment
  • Provides in-depth analysis of ONE specialized topic
  • Written by scholars or experts in the discipline
  • Peer-reviewed or refereed journals have an editorial board of subject experts who review and evaluate submitted articles before accepting them for publication.
  • A journal may be a scholarly journal but not a peer-reviewed journal.
  • Scholarly journals use this process to protect and maintain the quality of the material they publish. See an example from a journal publisher: WILEY's Peer Review Process

This is what a typical journal article looks like. The key components are highlighted.


Where to Find Journal Articles?

Library subscribes to a huge number of scholarly journals in different disciplines. You can use OneSearch, the Library's search engine, to find the articles in these journals based on the topic you have.

Watch this video to learn how this works.

Steps to Build a Search Statement more efficiently

From the video tutorial you have learnt how to search peer-reviewed articles using OneSearch - the Basic Search, where all keywords are typed in one line. Sometimes you may not be able to get satisfactory search results when your topic involves multiple concepts. This is when Advanced Search can help.

Advanced Search allows you to build a more structured search statement. This helps you find relevant results more efficiently. 

Advanced Search
  Enter a search term
Enter a search term
Enter a search term
  Add a New Line   Search

This is how Advanced Search looks like in OneSearch and many article databases. With the multiple lines structure, you can type in keywords representing different concepts in separate lines and specify the search field for each line.

You can also apply searching techniques, e.g. combine your search terms with Boolean operators (AND, OR, NOT) to make your search more precise.

 


Here are the 4 steps to build an effective search statement.

From the preliminary search, you may have identified a few keywords and related terms from your research question. Pick 2-4 core keywords that represent different concepts. The keywords are usually nouns or noun phrasesWatch this video to learn a few more tips about picking keywords. 

Example topic: "The impact of COVID on the hotel industry in Hong Kong".

The keywords picked could be:  COVID, hotel industry, Hong Kong

Go to OneSearch Advanced Search or an article database (e.g. Web of Science, Scopus) to build your search statement.

Use AND to combine the keywords so that the search results will include all these keywords.

To make your search more precise, you may:

  • Use quotation marks " " to enclose the phrase to search the terms as a phrase. This is known as a phrase search.
  • Specify search field, e.g. search within article title, subject, journal title. 


In our case: 

Advanced Search
  All Fields COVID
AND Subject "hotel industry"
AND All Fields Hong Kong
  Add a New Line   Search

If you run this search in OneSearch, you will notice there are very few results. This shows that the keywords you used may not be the keywords used in research papers. To make sure we do not miss out those studies, we need to expand our search by adding alternative keywords. 

Use OR to combine the alternative keywords (or synonyms) so that articles containing at least one of the keywords will be included in the results.

You may also:

  • Use truncations * to include variants of a word, e.g. travel* searches travel, travels, traveling, etc.
  • Use parentheses ( ) to enclose the phrase to specify the order (terms within parentheses will be executed first). 


In our case: 

Advanced Search
  All Fields COVID OR coronavirus OR pandemic
AND Subject "hotel industry" OR hospitality OR tourism OR travel*
AND Title Hong Kong
  Add a New Line   Search

Check search results in OneSearch and see the difference. Note that we changed the search field of "Hong Kong" to "Title" so that only articles with "Hong Kong" in their title will be retrieved. This again makes our search more specific.

The last step is to refine your search results using filters, e.g.

  • Peer-reviewed journals only
  • Publication year range
  • Subject category
  • and more

You can find similar filter options in OneSearch and many other article databases. 


Don't target for a perfect search statement on your first try! It is very common to refine your search statement until you retrieve a manageable number of relevant results. You may discover new keywords or even refine your research topic during the searching process.
