Help with Costs 4
Assessment of the cost-benefit of reformatting standard storage
media will vary from institution to institution. The following
issues indicate factors which may be taken into account before
deciding whether it is cost-effective:
- Stability of format (e.g. optical disks tend to be more
stable than floppy disks*)
- Storage capacity of the media
- Volume of material
- Ease of access if high use is anticipated.
- Copyright. Whether permission has already been received
from the owner to reformat to other offline or online storage.
- Operational considerations (e.g. it may be more efficient
to re-format all onto a common carrier rather than selecting
only certain categories)
*For advice on reformatting floppy disks see “Practical
Advice for Preserving Publications on Disk”, 1999,
