Fragility is susceptibility to damage by handling or storage e.g. accidental damage

This is one of the four Preservation Factors (Fragility; Longevity; Format Obsolesence; Holdings) that go to make up the concept of Urgency or Likelihood of Loss.

Each of these technical factors have been given a ranking of one to five: one being the most at risk to five the least at risk.

1 – Treat as Glass
2 – Very Fragile
3 – Breakable
4 – Needs Some Caution
5 – Hardy Medium

Treat as Glass – lacquer discs; wax cylinders
