A scholarly text is written by a researcher in order to present research. Researchers publish their text in order to describe their research results or to summarise the research of others. There are different types of scholarly texts and different ways to search for them. The library website guides you through it.
In a scholarly article, one or more researchers write and present their research. A scholarly article is published in a scholarly journal. This means, among other things, that the articles are reviewed by other researchers. Such scrutiny is usually called peer review or refereeing.
