Abstract: A method for managing an on-line catalog, including operating an on-line catalog system via an on-line catalog management interface, and displaying the on-line catalog on user interfaces by transmitting catalog information from the on-line catalog system to the user interfaces over a network in response to requests of end-users. The method further includes collecting data of usage by the end-users interacting via the user interfaces with the on-line catalog. A list of available actions for controlling operation of the on-line catalog is incorporated in the on-line catalog system, and in response to the data, one of the available actions is selected as an applicable action. The method also includes providing the applicable action to a catalog administrator operating the on-line system.
