MARC21 Format for Holdings Data

MARC21 Format for Holdings Data is a standardized way libraries record detailed information about their collections, such as copies available, location, and access conditions. It uses a set of coded fields within a digital record to efficiently communicate these details to different systems and institutions. This format ensures accurate sharing and management of holdings data across libraries and online catalogs, facilitating resource discovery and management. Essentially, it’s a structured, uniform method for libraries to describe their physical and electronic holdings electronically.
