In this paper, we present a technique called shallow copying on multimedia sources that can be done in a new authoring mechanism called virtual authoring. It can be used to create new documents by customizing and integrating existing multimedia documents without replicating them. Hence this mechanism provides the architecture to develop extended information layers on top of existing collection of multimedia documents.
