Subject Headings

How to find subject headings (1)


Due to the fact that the Library of Congress Subject Headings vocabulary is a a controlled vocabulary, in order to use it to research a particular topic, you need to find how the topic is represented in the Library of Congress’s terminology. (So in this tutorial, when we see near the top of the page, "How to find subject headings," this is short for, "How to find the subject headings that represent your topics.")

How does one go about doing this? Actually, there are a few ways.

Let’s consider an example. Suppose I want to find how the topic “Ergonomics” (which is the science of equipment design for the workplace for the purpose of reducing worker fatigue and discomfort) is represented in the Library of Congress’s Subject Heading terminology.
