MARC21 Format for Bibliographic Data

MARC21 (MAchine-Readable Cataloging) is a standardized digital format used by libraries to organize and share bibliographic information about books, journals, and other materials. It encodes data such as titles, authors, publication details, and subjects in a structured way that computers can easily process and exchange. This uniform system allows libraries worldwide to catalog, search, and manage collections efficiently, ensuring consistency and interoperability across different systems. Essentially, MARC21 acts as a universal language for library data, helping librarians and users access accurate and comprehensive catalog information seamlessly.
