What is a control number?

A control number is a unique identifier assigned to a particular item or object in order to help track and manage it. Control numbers are commonly used in libraries, archives, and databases to organize and retrieve information efficiently.

In library and archival settings, control numbers are typically assigned to books, documents, photographs, and other materials to help staff and users locate them in the collection. Control numbers can be alphanumeric or numeric, and may be generated using a specific system or format.

In databases, control numbers are also used to uniquely identify records and transactions. This helps ensure that data is managed accurately and securely, and that any changes or updates can be tracked and traced back to the original source.

Overall, control numbers play a crucial role in information management and organization, helping to streamline processes and improve efficiency in various industries and sectors.
