Inputs

Location
A pull-down menu containing all of the branches that belong to the Springfield Library. This menu currently contains only the main branch, but is expandable as the Springfield Library expands.
Floor
A decimal number of the form DD, where D represents a digit from 0 - 9. Thus, a particular book can only be on a floor from 0 - 99.

A pull-down menu containing the choices: {available, on loan, overdue, on hold, out of circulation} Only one of these choices can be selected.

Selecting 'OK' will close the message box. Once the ISBN number is error free the system checks to see if there is a book in the database with that ISBN number.

Once all errors are corrected (if there were any), the 'OK' button is pressed at which time the data for the book that will have a copy added is displayed. The user then preoceeds to enter in data for the appropriate fields and presses the 'ADD' button. If there are any errors with the data added, this will be displayed in an error window. Once all errors are corrected (if there were any), pressing the 'ADD' button will add the book copy to the database. If, at any time, the user wants to leave, clicking on the respective QUIT or CANCEL buttons will exit them from the window.
