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 handle a wide variety of information assets (e.g., electronic documents, audio, video), making them available to anyone with access rights, regardless of their physical location. Largely missing from this picture, however, is the ability to share paper-based information. Except for specific vertical applications (forms processing, records management, etc.), knowledge that exists on paper tends to stay on paper.
