The Cultural Heritage Community does not need an education in how quickly information can become obfuscated, obliterated, or impractical without proper preservation curation and migration – it is the very impetus for the existence of the community. The age of microfilm was a short blip on the historical timeline of Cultural Heritage Preservation, and already, much of the work done during this period is languishing in storage, inaccessible by its target audience with their modern expectations. Moreover, much of the work done on microfilm is now considered insufficient quality to be considered Preservation Grade.
Scanning an image and saving to a hard drive is trivially easy; creating a Preservation Digital Object (PDO) requires careful consideration and continuous vigilance. Technology rapidly evolves, especially those technologies which control how digital information is created, stored, and retrieved. The goal of a PDO is to capture, wrap, and describe data in such a way that enables migration between storage systems, with the specific ability to be indexed and deciphered by future access systems.
