Many of the same distinctions apply to books. The author’s credentials, the writing style, the presence (or lack) of footnotes, and the type of publisher (university press or mass-market publishing house) should all be looked at as part of the evaluation of the quality of a particular book.
Scholarly articles are usually one of five major article types: empirical studies, review articles, theoretical articles, methodological or case studies.
A typical article will have an abstract to summarize the article. It will introduce the problem, present a thesis statement followed by the body/methodology. If there is raw data, there will be a results section or, if not, it could be a findings section. A discussion section interprets the results in light of other studies. The conclusion restates the thesis and suggest future research
