The Ultimate Digital Preservation Guide, Part Five — What is worth preserving? (Genealogy’s Star)

Genealogy’s Star: The Ultimate Digital Preservation Guide, Part Five — What is worth preserving?. “Digital preservation has two main challenges that are not shared with paper books: device obsolescence and file format obsolescence. Unlike a book sitting on a shelf, a file on a storage media such as a hard drive can become unreadable merely because of the passage of time. This occurs as the devices used to store the information become inaccessible (think floppy disks) or because the operating systems and programs change over very short periods of time (think of an old computer program you can no longer use on any present-day computer). To preserve the information in a digital file, it must be periodically migrated to newer hardware, programs, operating systems, and file formats as those change over time.”
