Digital scanning is a technology enabling text, character, handwriting or image documents to be digitally copied, stored, altered, reprinted, transmitted or published on the internet.

Like any technology, the cultural impact of digital scanning is potentially good or bad. Portable, hand held scanners are useful for researchers, replacing the less convenient photocopy machines. But scanning could be misused by the unscrupulous, especially with so-called “floating documents,” which in many organizations are destroyed after a single use.

Most would think that digital scanning is a new idea. But, incredible as it may seem, it has roots that go back into the 1800s.¹
