How to Find Sources | Scholarly Articles, Books, Etc.

It’s important to know how to find relevant sources when writing a paper, literature review, or systematic review.

The types of sources you need will depend on the stage you are at in the research process, but all sources that you use should be credible, up to date, and relevant to your research topic.

There are three main places to look for sources to use in your research:

• Research databases
• Your institution’s library
• Other online resources

Research databases

You can search for scholarly sources online using databases and search engines like Google Scholar. These provide a range of search functions that can help you to find the most relevant sources.

If you are searching for a specific article or book, include the title or the author’s name. Alternatively, if you’re just looking for sources related to your research problem, you can search using keywords. In this case, it’s important to have a clear understanding of the scope of your project and of the most relevant keywords.

Databases can be general (interdisciplinary) or subject-specific.

• You can use subject-specific databases to ensure that the results are relevant to your field.
• When using a general database or search engine, you can still filter results by selecting specific subjects or disciplines.

Example: JSTOR discipline search filter

Check the table below to find a database that’s relevant to your research.

Google Scholar

To get started, you might also try Google Scholar, an academic search engine that can help you find relevant books and articles. Its “Cited by” function lets you see the number of times a source has been cited. This can tell you something about a source’s credibility and importance to the field.

Example: Google Scholar “Cited by” function

Boolean operators

Boolean operators can also help to narrow or expand your search.

Boolean operators are words and symbols like AND, OR, and NOT that you can use to include or exclude keywords to refine your results. For example, a search for “Nietzsche NOT nihilism” will provide results that include the word “Nietzsche” but exclude results that contain the word “nihilism.”

Many databases and search engines have an advanced search function that allows you to refine results in a similar way without typing the Boolean operators manually.

Example: Project Muse advanced search

Library resources

You can find helpful print sources in your institution’s library. These include:

• Journal articles
• Books
• Encyclopedias
• Newspapers and magazines

Make sure that the sources you consult are appropriate to your research.

You can find these sources using your institution’s library database. This will allow you to explore the library’s catalog and to search relevant keywords. You can refine your results using Boolean operators.

Once you have found a relevant print source in the library:

• Consider what books are beside it. This can be a great way to find related sources.
• Consult the index and bibliography to find the bibliographic information of other relevant sources.

Other online sources

You can consult popular online sources to learn more about your topic. These include:

• Websites
• Crowdsourced encyclopedias like Wikipedia
• Blogs

You can find these sources using search engines. To refine your search, use Boolean operators in combination with relevant keywords.

However, exercise caution when using online sources. Consider what kinds of sources are appropriate for your research and make sure the sites are credible.

Look for sites with trusted domain extensions:

• URLs that end with .edu are educational resources.
• URLs that end with .gov are government-related resources.

Other sites can still be used, but you should evaluate them carefully and consider alternatives.

Frequently asked questions about finding sources

How can I find sources to use in my research?

You can find sources online using databases and search engines like Google Scholar. Use Boolean operators or advanced search functions to narrow or expand your search.

For print sources, you can use your institution’s library database. This will allow you to explore the library’s catalog and to search relevant keywords.

How do I find scholarly sources?

It is important to find credible sources and use those that you can be sure are sufficiently scholarly.

• Consult your institute’s library to find out what books, journals, research databases, and other types of sources they provide access to.
• Look for books published by respected academic publishing houses and university presses, as these are typically considered trustworthy sources.
• Look for journals that use a peer review process. This means that experts in the field assess the quality and credibility of an article before it is published.

How do I search research databases efficiently?

When searching for sources in databases, think of specific keywords that are relevant to your topic, and consider variations on them or synonyms that might be relevant.

Once you have a clear idea of your research parameters and key terms, choose a database that is relevant to your research (e.g., Medline, JSTOR, Project MUSE).

Find out if the database has a “subject search” option. This can help to refine your search. Use Boolean operators to combine your keywords, exclude specific search terms, and search exact phrases to find the most relevant sources.

What types of sources are used in academic research?

There are many types of sources commonly used in research. These include:

• Websites
• Books
• Journal articles
• Newspapers
• Encyclopedias

You’ll likely use a variety of these sources throughout the research process, and the kinds of sources you use will depend on your research topic and goals.

What is the difference between a scholarly and a popular source?

Scholarly sources are written by experts in their field and are typically subjected to peer review. They are intended for a scholarly audience, include a full bibliography, and use scholarly or technical language. For these reasons, they are typically considered credible sources.

Popular sources like magazines and news articles are typically written by journalists. These types of sources usually don’t include a bibliography and are written for a popular, rather than academic, audience. They are not always reliable and may be written from a biased or uninformed perspective, but they can still be cited in some contexts.
