What is a subject heading and why is it important to searching for mixed race materials? After a book is published, it is cataloged and tagged with Library of Congress (LOC) subject terms so that researchers looking for these materials can find everything that has been tagged with these terms. If you know the subject terms that indexers use to tag books on a given topic, then you can do a very targeted search on that topic in the Library's catalog.
The Library's catalog is a database of virtually all of the materials that the Library owns, including electronic and paper books, videos, DVDs, journal titles (not the individual articles within the journals), etc.
To search the catalog, paste the following search into the search engine: subject:("racially mixed" OR "interracial marriage")
For help with searching the catalog, please contact Ask a Librarian.
