In contrast to reference works such as dictionaries, encyclopedias, and handbooks, a monograph or anthology is usually intended to argue a controversial point.
Monographs are so named because they focus on developing a unified argument about a topic.
An anthology contains essays by multiple authors, typically arguing different points oriented toward a particular theme. Each essay in an anthology is understood as a singular source, and tend to be short and more tightly-argued like an academic journal article.
Both monographs and essays will be listed in EBSCO database results.
