What does microfilm mean?
Microfilm is a photographic reproduction of documents, photographs, or other images on film at a much smaller scale than the originals. It was widely used by libraries, archives, government offices, and publishers because it could store large quantities of material compactly while allowing readers to enlarge individual pages with a microfilm reader. The term can also mean the film itself, and it may be used as a verb: to microfilm a document means to reproduce it in this form. Microfilm is valued for preserving historical records, although handling, fading, and the difficulty of reading small text can be disadvantages. Digital imaging has largely replaced it in active use, yet microfilm collections remain important in many archives and special collections, particularly for newspapers, manuscripts, and other fragile materials.
A photographic reproduction of documents or images reduced in size on film, or the film containing those reproductions.

Where does microfilm come from?
Microfilm was formed in the early 20th century from micro-, a combining form meaning small, and film, referring to the photographic film on which the images were recorded. The prefix micro- comes from Greek mikros, meaning small, and is also the source of related words such as microscope and microorganism. The compound follows the broader early 20th-century development of microphotography and was especially associated with documentary preservation and compact archival storage.
