Digitization appears as another of the answers to the problems of conservation and dissemination in the documentary and bibliographic field, offering important advantages over other techniques.
This new technology consists of the capture of images or text documents through a scanning process and their subsequent storage on an optical or magnetic medium. The digitized document is immediately accessible and reproducible through a computer, without loss of quality in its successive copies or accesses.
Microfilming consists of copying text and/or image documents on film support, on a reduced scale.
