Potrzeby w zakresie przechowywania zbiorów na podłożu papierowym i ich konserwacji na przykładzie Biblioteki Polskiej w Paryżu

The article is the outcome of the author’s stay at the Polish Library in Paris in 2000 for the purpose of examining collections of paper-based objects and the state of their preservation. The Library gathers works by Polish authors connected with France as well as those by artists originating from the French, English or Italian schools. The article discusses assorted factors affecting changes of the physical and chemical properties of paper. The rate of those transformations depends on external and internal factors. Further on, the author considered ways of minimalising the impact of those factors by means of suitable conditions of storing the collections. Another topic, alongside prophylaxis, was conservation intent upon restoring the “original appearance” of paper-based collections.
