An image, such as a photograph or x-ray, which is stored exactly as recorded by the camera or x-ray film, as a “picture”. In this form, the image can only be retrieved as the picture of the object, text page, or graphic; it cannot be retrieved by electronic searching of the image itself, nor, if text, can its contents be handled electronically, as with a wordprocessing computer program. In fact, an analog image is always in “hard copy” form, whether it’s on paper, film, papyrus, or other physical material. To retrieve the analog image electronically, there must be a separate and parallel system in digital form, which indexes the analog image in some fashion. Microfilming, for example, captures pictures of the pages, and to retrieve specific pages, an external indexing system is required to find the pages desired by the user.
