Biodeterioration of library materials is a worldwide problem in archives and libraries. Investigation of biological agents (quantitatively and qualitatively) as well as environmental factors that affect the survival and persistence of microorganisms, are the main parts of preventive conservation. Therefore, we studied the biological pollution in repositories and other parts of the Documentation Center and Library of the Cultural Heritage and Tourism Research Institute and evaluated the environmental factors (temperature, relative humidity) in order to preserve paper works.

Method and Research Design: 

Quantitative and qualitative investigations of biological contaminants (bacteria and fungi) were performed using sedimentation method (passive method). In addition, environmental factors (temperature and relative humidity) were monitored in audiovisual and records repositories.

Relative humidity and temperature variation rates were high and non-standard in the audiovisual and records repositories. Biological studies showed that the fungal and bacterial contamination level in the library repository was higher than the alert level. The most frequent bacterial isolates were Bacillus and Staphylococcus and the dominant fungal isolates belonged to the genera Aspergillus, Penicillium, Alternaria, Cladosporium, most of which have a high potential to produce decomposing enzymes.

This research has been carried out with the aim of improving the quality of the method for documentation of paper-based works and creating online databases through general-research IDs، conservation-repair IDs، and status forms. Methodology/Approach: The research method included library study، field study and study of electronic papers and books. This was carried out to study the background of documentation and the standard structure of digital documentation and presenting a standard pattern for paper-based works. The findings and conclusions of this research show that comprehensive documentation – preparing a standard ID for paper-based works – not only protects the data but is also an important and basic measure in risk management (as one of the strategies for preventive conservation). Furthermore، the database provides researchers and experts with online data about paper-based works immediately.
