kataloglanr

Kataloglanr is a term used to denote a catalog number, a unique identifier assigned to a single item within a catalog or inventory. In library, archival, and museum contexts, the kataloglanr functions as a stable reference that enables precise retrieval and management of holdings.

In practice, a kataloglanr is assigned when an item is entered into a catalog by a library, archive, or museum. It is typically stored in the item's metadata and may be included in public catalog displays, shelf lists, and internal inventories. The number helps distinguish items that share a title or author, and it supports processes such as lending, conservation, and rights management.

Most kataloglanrs are alphanumeric and may include prefixes or codes that indicate collection, accession year, or repository. Formats vary by institution; some numbers are permanent while others may be reassigned during accessioning or relabeling. In digital catalogs, a kataloglanr can be used to link metadata to digital objects, versions, and related records.

Although many catalogs use a field or element labeled as catalog or control numbers, "kataloglanr" is not a universal standard. The exact label and handling depend on language, local cataloging practices, and metadata schemas such as MARC, Dublin Core, or MODS. In various languages, equivalent terms include catalog number, katalognummer, or catalog no.

An illustrative example is a kataloglanr such as KAT-2024-00123, which uniquely identifies the item within its institution's collection.
