Some conceptual and theoretical aspects related to the conservation of documents and to the policies for the preventive conservation of collections are approached. The terms "conservation" and "preservation" are defined. The main factors of document deterioration are studied: temperature, humidity, light, manipulation, contaminants, fungi, insects, paper, inks, among others. Finally, the policies of preventive conservation and the conservation diagnoses are dealt with.
