What is Microform?
'''Microform''' is a name given to special [[photographic film]]s. Microforms contain reduced [[image]]s of [[document]]s. Usually, documents stored on microform are reduced about 25 times. Microform is mainly used for archival purposes. There are three common formats: *'''Microfilm''', which comes in [[reel]]s of film. *'''Aperture card''', This contains additional digital data (as a [[punch card]]). *'''Microfiche''', a flat sheet with many pages. Properly stored (room temperature, 50% humidity), microform should be able to last up to 500 years. == Images == <gallery> Image:Positive roll film.jpg|A roll of (positive) microfilm Image:Aperture card.JPG|An aperture card Image:Microfiche card.JPG|A microfiche (flat sheet) </gallery> {{stub}} [[Category:Photography]] [[Category:Storage devices]]
