A work queuing system and method to increase the availability of an automated data storage library for accessing and storing data storage media. At least one accessor moves the data storage media among storage shelves and data storage drives in response to work requests. The work queuing system comprises a communication processor node for receiving the work requests and for broadcasting the work requests, e.g., over a common bus network, to a plurality of work processor nodes coupled to the communication processor node and coupled to each other. Each work processor node responds to the broadcast work requests, establishing a work queue of jobs. At least one of the work processor nodes selects ones of the jobs in the work queue for an accessor and directs the accessor to conduct the selected job. The work processor nodes then synchronize the work queues.
