Subiect: The materials from which the books are made are generally organic in nature, easily degraded under adverse conditions. The main concern of those who work with antique books is to ensure permanence, which is very difficult to achieve if they do not take measures to prevent the preservation of collections.
To stop the evolution of degradation processes or to heat the settlers by a new one, it is bad to take preventive conservation measures, an example being the conservation actions undertaken in two ancient stacks of books and documents in Alba Iulia.
