A general introduction to a topic, use an Internet search
Very current news, use an Internet search
Current or older/archived news, use newspaper databases
Scholarly content, use:
Use words that would be used in your desired result. Sometimes, academic language is different than the common language used on the web. For example:
Use quotation marks to find results that only have those words appearing right next to each other. This gives you fewer, more relevant results. For example:
Most of the content you find with a search engine is not considered scholarly. It may be a news or blog article, but to professors, articles often means academic, peer-reviewed articles.
Most library search tools will let you limit to scholarly content. Google and Google Scholar do not.
Ask your professor about what type of article source you can use.
