Eugene Barnum Power was an American entrepreneur, philanthropist, founder of the modern microfilm industry, and pioneer in the use of microfilm for the reproduction of scholarly publications.

A microform is a scaled-down reproduction of a document, typically either photographic film or paper, made for the purposes of transmission, storage, reading, and printing. Microform images are commonly reduced to about 4% or 1⁄25 of the original document size. For special purposes, greater optical reductions may be used.
