The Library of Congress establishes standard terms to describe the subjects of items in the library catalog. Searching with these standard terms can be more precise than guessing at search terms.
Subject headings are often made more explicit with subheadings. Adding a subheading term such as "ethical" to a topical search will focus results.
More subheadings....
-- Political aspects
-- Psychological aspects
-- Religious aspects
-- Religious aspects -- Christianity
-- Religious aspects -- Islam
-- Social aspects
Include "ethical" in any search with topical words.
Examples:
euthanasia ethical
abortion ethical
business ethical
This works because the subheading "Moral and ethical aspects" is often used to describe books on these topics. See examples below .
When ethical issues related to a specific topic are addressed, the subheading "Moral and ethical aspects" is added to the topic. Examples:
Consumption (Economics) -- Moral and ethical aspects
Economics -- Moral and ethical aspects
Imperialism -- Moral and ethical aspects
Motion pictures -- Moral and ethical aspects
War -- Moral and ethical aspects
Wealth -- Moral and ethical aspects
