It's important to note that there is sometimes a lag in academic language--for example, what is used in peer-reviewed, scholarly sources compared to terms that are used colloquially or in natural everyday language.
Be aware that when subject headings in catalogs and databases may use outdated terminology or assign inaccurate or incorrect terms (see, for example, the article, "The Power to Name: Representation in Library Catalogs").
When searching most Library online Catalogs (i.e., OneSearch, CSU+, and WorldCat) use Library of Congress (LC) Subject Terms to describe the contents of a book. Using these "official" terms or "controlled vocabulary" can sometimes improve search results.
You can use colloquial AKA "natural" or everyday language with some results but the more formal terminology (subject terms) or a combination may yield greater results.
