Behind the Scenes:
Meet the Metadata
Behind every item in the library catalog is a hidden layer of information called metadata. For most public libraries, this metadata layer is a MARC (MAchine-Readable Cataloging) record and includes details like a book’s title, author, subject, publication date, and format. Metadata is what makes it possible to search the catalog and quickly find exactly what you need.
A MARC record does more than just identify Charlotte’s Web by title and author. It also connects the book to subjects like friendship, farms, and children’s literature. The next time you’re browsing the catalog, try changing your search type from “keyword” to “subject” – the search is now looking specifically for subjects included in a MARC record.
Good metadata matters because it helps patrons find materials easily and accurately. Creating and maintaining metadata is detailed work done behind the scenes by catalogers. While you may never see a MARC record, you benefit from them every time they search the catalog, place a hold, or discover your next favorite book.
