The objective а study of the aging processes of library documents on various types of paper that have been in an emergency compared to documents that have not ex-perienced a negative technological load. The research methodology consists in the application of instrumental, mathematical and applied methods, which allows to most fully reveal the tasks and prospects of further storage of documents on traditional media that have undergone negative environmental influences. The scientific novelty of the work is to expand ideas about the features of long-term storage of documents on tra-ditional media that have been in extreme conditions. For the experiments, the types of paper that were used as the material basis of the documents subjected to the greatest extreme technogenic load – excessive wetting, freezing, and drying — were selected as model samples. This is rag paper of the 17th – 18th centuries, newsprint of the middle of the 20th century, printing paper No. 1 of the middle of the 20th century. with cer-tain physicochemical and capillary hygroscopic properties. The operational properties of these model paper samples were determined by mechanical strength indicators: frac-ture strength at repeated kinks, destructive force and tensile strength, because it is these indicators that most accurately characterize the processes of natural aging of the mate-rial. Conclusion. Providing targeted recommendations for categories of documents on traditional media that have undergone anthropogenic load depending on the type of paper, the degree and nature of the impact of negative factors in an emergency. Also relevant are ways of protecting binding materials in an emergency, because the frameis often the first to experience the consequences of its negative impact. For a positivesolution to the problem of ensuring the safety of documents on traditional media that have undergone anthropogenic load, it remains relevant to implement all possible varie-ties of preventive conservation as a guarantee of the effective safety of library collections.
