Browsing is an effective strategy for gaining a comprehensive sense of the NYPL Research Catalog. The
Subject Headings index draws from the Library of Congress Subject Headings (
LCSH), which are descriptive authorities created by the Library of Congress and used by libraries to group similar materials together by subject. Each item in the catalog is typically assigned at least one relevant Subject Heading, and clicking through the hyperlinked Subject Headings is a great way to discover more materials about that subject.
