In today's Internet-driven, knowledge-based economy, quick access to important information is critical to day-to-day business functions. Document and content management systems now handlea wide variety of information assets (e.g., electronicdocuments, audio, video), making them availableto anyone with access rights, regardless of their physicallocation. Largely missing from this picture, however, is theability to share paper-based information. Except for specificvertical applications (forms processing, records management,etc.), knowledge that exists on paper tends to stay on paper.
