First, incoming orders are checked for correct book titles, author's names, and other information and then batched into other book orders from the same bookstore to determine how may copies can be shipped through the ware house. Also, the credit status of each book stores is checked before shipment is authorized. Each shipment has a shipping notice detailing the kind and numbers of booked shipped. This is compared to the original order received (by mail or phone) to ascertain its accuracy. Thedetails of the order are normally available in a special file or data store, called "Bookstore Orders”.
