Subject Headings are terms that are most commonly used to describe the topic that a resource covers. Unlike keywords, which are user generated, subject headings are created and maintained by an authoritative institution. Since Williams Libraries, and most academic libraries, organizes our resources using the Library of Congress Classification, we also utilize Library of Congress Subject Headings to provide access to our collections by subject. Subject headings are arranged systematically, and can be useful tools to help browse the collection by topic. Subject headings for each resource are located in the "Details" section of the catalog record, under "Subjects."
Below are examples of Subject Headings that may be used as starting points for your research projects. Clicking on a subject below will take you to a list of resources that cover the listed subject.
