Preservation: practical information sheets

Preventive preservation

Preventive preservation refers to the range of direct and indirect actions undertaken on collections and aimed at preventing degradation and prolonging document life spans: carrying out environmental checks, preparing and monitoring an emergency plan, transferring to alternative media (micrography for archiving, digitization and printing substitute documents for consultation), etc.

Environment and preservation of library collections

By Astrid-Christiane Brandt and Jean-François Foucaud
(Recommendations on the Book and Reading Directorate (Direction du Livre et de la Lecture/DLL) website)

Environmental conditions and warehousing methods have a significant influence on the preservation of graphic materials. Initial preventive measures consist of carrying out environmental checks and ensuring that suitable storage conditions are in place. Degradation can be slowed by acting on factors such as temperature, relative humidity, light, biological decay agents (mold, insects, and rodents), and chemical and mechanical decay agents (pollutants and dust). It is also possible to avoid or limit degradation caused by human agents.
