Harvard has adopted a new process to preserve its digital content. Using digital forensics, which was developed to create authentic, unimpeachable data suitable for use as evidence in criminal trials, the archivists retrieve data from obsolete formats using three components: the hardware, the software, and the technician. The first step is imaging which creates a copy of the source medium and replicates the structure and contents independent of the file system. Once the content has been taken from the carrier it can be processed. Then a decision is taken about access, which will be by migration or emulation. Even when the content is retrieved the original media may be retained as advancements are starting to allow the retrieval of content on formats that were previously written off. The archivists are agreed, however, that the problem of obsolescence will not disappear as technology continues to race ahead.
