Which term refers to the set of letters, numbers, and symbols used to locate a book on library shelves?

• A. Call
• B. Shelf code
• C. Catalog entry
• D. Index number

Answer: (A)

Locating a book on library shelves relies on the call number. This is the code printed on the spine of the book that uses a combination of letters, numbers, and sometimes symbols to place the item in a specific spot within the library’s organization system (like Dewey or Library of Congress). The call number groups books by subject and, within that subject, may reflect author or title, so you can follow the sequence on the shelves to reach the exact item. It’s different from a catalog entry, which is the bibliographic record you see in the library catalog, and it’s not an index number, which serves indexing purposes rather than shelf placement. Some libraries might use a vague “shelf code” in internal notes, but the standard term for the locator on the shelf is the call number.
