Abstract: A computer/software system is described which enables a user to produce and display an audio/visual application using a library of image, audio and story objects. The system creates a first library data file which includes a list of application files. It then creates a bill of materials listing for each application file, each listing comprising a first field area for an object name and a second field area for a path definition to where said object is listed in another application bill of materials and physically exists. The system then runs the application and accesses all objects listed therein, any object with a path listing, being accessed from the file indicated by the path definition. A method of searching, which employs the path definitions is also described.
