The literature supply subcommittee maintains a stock of NA books and pamphlets that can be purchased by local groups at the monthly ASC meeting. In some areas, this subcommittee may consist of only one or two people. In other areas, it may involve as many as half a dozen members who process group orders, monitor stock levels, and reorder materials from the local NA office or the World Service Office. To maintain accountability for all area funds, most areas ask their treasurer to serve as cashier for literature sales. The subcommittee then goes to the treasurer for a check when it has to reorder stock. To help organize the job of processing group orders, tracking inventory, and reordering depleted items, contact the World Service Office for available resources.
