Preventive Conservation

Encompasses all Brazilian National Library’s collection, regardless its state of conservation, and includes measures and actions with the intention of minimizing future deteriorations or losses. Examples: necessary procedures for handling and support, sanitation, storage, preservation, packaging and transport, security, environment control (light, humidity, atmospheric pollution and pests control), emergency plans and staff training.

Restorative Conservation

It is characterized by the actions directly applied on the heritage, with the purpose to stop harmful processes or to strengthen its structure.

Examples: recovery of damaged bindings, torn pages repair, grafts in missing parts of the internal layout or the cover, and planning of documents.
