A system for controlling removal of articles from a facility by authorized users transmits data to, and receives data from, an article inventory control system and an electronic article surveillance system, either or both of which may be pre-existing. The inventive system comprises a terminal which identifies the user and article, transmits the user and article identification data to the article inventory control system, receives article removal authorization data from the article inventory control system, verifies the identity and number of articles to be removed, and enables the user to remove the article through the electronic article surveillance system. The preferred embodiment is adapted for a library, and is designed to provide library patrons with the ability to check books out of the library without staff assistance.
