Our collection holds more than 40 million items and occupies almost 380,000m in shelf space.
The collection includes:
- paper-based files
- audiovisual records
- digital records
- bound volumes
- maps and plans
- other objects
We preserve items in two main ways:
- We provide quality long-term records storage.
- We target and care for at-risk records.
Quality long-term records storage
Quality long-term records storage slows the physical records' ageing process. This gives us time to manage the preservation of these records.
The digital archive is stored on 2 independent systems to prevent data loss.
Targeting at-risk records
Records considered at-risk are:
- chemically unstable
- in poor condition
- regularly accessed
Our preservation policy guides conservation staff working in:
- treating records
- preventing damage
- preparing exhibitions
- digitising physical records for preservation
- preserving audiovisual records
- preserving digital records
