MARC 21 (MAchine-Readable Cataloging) is a set of standards for encoding descriptive information about library materials (books, serials, computer files, maps, music, etc.) in a machine-readable format. It's primarily used by libraries and other institutions to create and share bibliographic records, enabling resource discovery and catalog management.
Whether you're looking to get your foot in the door, find the right person to talk to, or close the deal — accurate, detailed, trustworthy, and timely information about the organization you're selling to is invaluable.
