@rjs is right about the problems of maintaining those kinds of records. Printed paper is unstable unless you use acid-free paper and control the humidity of the storage location. Computer media changes every few years. CD-ROMs were supposed to last 100 years, it turns out the dyes used in CD-RW discs are somewhat unstable, and who even has a CD reader on their computer today, much less 40 years from now. I have genealogy documents that I scanned in 1993 at the then-impossible resolution of 300dpi, saved as jpgs, and I also took high quality B&W photos with technical film (I had access to a darkroom back then). Guess which format is higher quality today?
