The nineteenth century witnessed profound transformations in the technology of paper production; consequently, paper lost its age-resistance and books, periodicals and documents from that period onwards represent, as a rule, an unsatisfactory state. A mass–scale deacidification - the only known way of limiting losses in collections from the two centuries - was inaugurated in Poland thanks to the Government 'Acid paper' Programme, realized in 2000-2008. Books and other prints are treated with the Bookkeeper method applied at the National Library in Warsaw and the Jagiellonian Library in Krakow, while sheet documents are treated with the Neschen method in the two above-mentioned libraries and in four archives: in Warsaw, Katowice, Gdynia and Milanówek near Warsaw. Furthermore, statistical research conducted as part of the programme established that in Poland at least 43 mln books and 200 kms of acts must be deacidified, which, on a national's calve, comprises about 94% of library and archive resources from the last two centuries. The optimistic aspect of the issue lies in the fact that the publication of books with non-acid paper was inaugurated in Poland at the end of the last century; this means that the number of library resources threatened with acid hydrolysis is not growing. The article also analyses studies relating to the state of preservation of nineteenth and twentieth-century collections with a paper base.
