Preservation, Conservation and Library Security
What the exam tests
This domain tests preventive care, remedial treatment and security of library materials. Questions often describe damage or a hazard and ask for the first appropriate action.
Core rules and concepts
- Preservation: preventive measures that slow deterioration, such as good shelving, dusting, climate control, pest control, binding and digitisation.
- Conservation: remedial treatment of damaged items, such as repair, deacidification or rebinding by trained staff.
- Agents of deterioration: physical wear, light, heat, humidity, dust, insects, rodents, mould, water, fire and human negligence.
- Environment: keep temperature moderate, relative humidity around 45–55%, avoid direct sunlight and provide air circulation.
- Security: access control, CCTV, RFID or electromagnetic gates, locking shelves, staff training, fire extinguishers and an emergency plan.
- Digital preservation: backup, file-format migration, checksums and access copies.
Worked example
After the monsoon, mould appears on books in a closed room. First isolate the affected books, dry them in a ventilated shaded area, brush off dry mould with a soft brush, reduce humidity, improve air circulation and consult a conservator for valuable items. Reasoning: mould spreads through spores and moisture; direct sunlight and heat can warp or fade books, so shade drying and humidity control are safer.
Traps
Preservation is not only repair; prevention comes first. Do not use water on an electrical fire. Do not keep books in damp, sealed cupboards. Security is not only theft prevention - it includes fire, water, pest and digital risks.
