Lost Is Not Missing: Understanding Alma's Item Processes

The words we use every day do not always mean the same thing inside the systems we use.

"Lost" and "Missing" are good examples.

In everyday library language, we often use these words somewhat interchangeably. A book that is not where it should be might be called lost. So might a book a patron never returned.

In Alma, those are two different situations, and the workflow that follows depends on what the system is actually tracking.

Lost is connected to circulation.

A lost item is an item that was checked out to a patron and has entered the lost item process, either because the patron reported it lost or because the loan aged past the library's lost item threshold. In this case, the system is tracking the relationship between the item and a circulation transaction.

Lost starts with an event we know about: the item was checked out, and it did not come back.

Missing is an inventory problem. A missing item is one the library expects to have but cannot currently locate.

Examples in our library include:

• A requested item cannot be found during retrieval.
• A shelf reading session reveals an item is not where it should be.
• A patron requests help searching for an item they are unable to locate in their shelf browsing.

A missing item is not necessarily lost. It may have been reshelved incorrectly, be waiting in processing, or have been moved without the location being updated.

Missing starts with uncertainty: the library expects the item to be here, but it cannot be found.

A lost item leads back to a circulation process.

A missing item starts with a search.

The difference matters because the work begins in different places. Lost starts with a history. Missing starts with a question.
