Heritage Microfilm keeps today's news fresh for years and years. The company has built a business converting newspaper pages to microfilm reels, which are then stored in its temperature-controlled vault. The archivist also has the ability to create CD-ROMs. Heritage Microfilm's sister company, NewspaperArchive.com, provides scanning and digital imaging services that allow newspapers to publish archived materials online once they have been converted to microfilm. Heritage Microfilm's online vault contains more about 300,000 reels of preservation microfilm searchable by publication, city, or state. Its polyester-based microfilm boasts a 500-year life expectancy.
