MARC21 Formats

MARC21 (Machine-Readable Cataloging) is a standard format used by libraries to organize and exchange catalog information about books, journals, and other resources. It structures data into specific fields and codes, allowing library systems to accurately describe items—like titles, authors, publication dates, and subjects—in a consistent way. This standardization makes it easier to share and retrieve catalog data across different libraries and digital systems, ensuring users can find and access resources efficiently. Essentially, MARC21 acts as a universal language for library cataloging, facilitating smooth information management and exchange.
