Q. Is there a way to search for articles in one particular language?

Yes. Many of the databases allow this.

In JSTOR, you need to select "Advanced Search" and you'll see a dropdown box where you can select one particular language.

Some EBSCO databases have a "Language" box on their "Advanced Search" screen. Most EBSCO databases allow you to limit by language before or after you perform the search. Look in the top bar of the page and on the right you'll see "Languages."

Often, searching for a word in a different language is a quick way to find these kinds of articles.

You can set the preferences for Google Scholar to only search for pages written in a specific language. Go to Google Scholar, select Scholar Preferences at the top right then select your language.

You can also perform an advanced search in WorldCat Discovery for content in a foreign language.

If you are looking for articles in Spanish, Italian, German, French, or Chinese, each of these departments has a LibGuide with lists of suggested journals and databases for their language.
