The type of holdings which we store in the archive are principally paper-based materials. As it is well known, paper deteriorates and is subject to natural aging. By optimal storage conditions and care in handling, the deterioration process can be slown down. However signs of damage may appear in the documents such as: grime, folds, cracks, losses, stains, discoloration, mold, foxing, adhesive staining. Every document that needs to be  restored represents considerable costs for the archive.
