Additional Jury Comments

This entry is highly dependent on who is looking after the portable media but made more difficult over time. The lack of granularity in the definition means that only general advice can be offered such as to refresh media. In time it may yet be more useful to split all storage media (maybe 100 items long) with an indication of how long these can be expected to last. In many cases obsolete media can be recovered by specialist companies but the cost of employing them can become an aggravating condition.
