accession numbers

An accession number is a unique identifier assigned to a specific item, such as a library book, a museum artifact, or a scientific sample, when it is added to a collection or database. It helps organize, track, and retrieve that item efficiently. Think of it like a serial number that distinguishes one item from all others, ensuring easy reference and record-keeping. Accession numbers are essential in managing large collections, providing a consistent way to document and access individual items over time.
