Device used to project and magnify images in microform
A microfilm reader is a device used in projecting and magnifying images stored in microform to readable proportions. Microform includes flat film, microfilm, aperture cards, microfiche, and ultra fiche. Using open reels or cassettes, microfilm is often used as a way to store many documents in a small space. It has become increasingly prevalent in the development of films, as well as storage of archived newspapers. With the invention of microfilm, microfilm readers soon developed. With the increasing popularity of computers, microform has decreased in use. However, many library archives still remain in microform.
