The intent of this wiki is to provide you, the end user, with valuable information that may aid you in understanding a paperless office. Specifically, we touched on basic concepts such as the meaning, historical background, philosophy, pros and cons, technology, costs, tips, how-to-links and the like. Because we are not experts in this field and our knowledge of this topic is minuscule, we have conducted extensive research and evaluated online information sources to provide you with the most authoriative, objective, reliable, timely, and extensive coverage on the topic of the paperless office.
