Atriuum Mobile Interface (AMI) is an app designed to work in conjunction with the Atriuum Library Automation System. This app allows the librarian to handle basic circulation needs without being tied to the circulation desk: check a book out on the fly, check in a stack of books left on a table without carting them back to the desk, scan a book lost in the hall to find out who it belongs to, and quickly show patrons their status. All are possible in AMI.
