Abstract


Libraries and archives house a wide variety of documents made of materials of vegetal and animal origin: unbound papers and books, manuscripts and printed books, photographs (negative and positive), prints, maps, available to the public for reading needs, study and information. These materials are often subject to fluctuations in environmental and micro-environmental parameters. For this reason, it is essential to implement constant monitoring and control of environmental conditions and potential deteriogens in order to slow down deterioration processes.

The monitoring of the microbial degradation of paper documents in the Historical Archives of Palermo Astronomical Observatory has revealed microorganisms (bacteria and fungi) that may be considered responsible for damaging the items examined, thus enabling an evaluation of the real risks and the proper methodologies to use to avoid future recolonization.
