What is important in the conservation of paper records is that the records' initial features (chemical, physical, and biological) should not change through the pass of time. Selecting proper conservation methods and materials can prevent such changes to some extent. It seems that the adhesives used for repairing records may help the absorption and development of biological agents by preparing the proper environmental conditions. The aim of this research is to study the extent to which the adhesives used in repairing Iran's paper records affect the absorption and development of biological agents under standard environment conditions. This includes measuring the amount of development of microorganisms in each of the adhesives and the samples being repaired by them and comparing them with the non-repaired control samples. The most popular adhesives used for repairing paper records in Iran are traditional adhesives (including asphodel glue and starch) and synthetic adhesives (including Carboxymethyl Cellulose and Texicryl). Therefore the research population consists of handmade and machine-made papers and four types of adhesives typically used for repairing paper records. In order to carry out laboratory experiments, similar samples were separated from handmade and machine-made papers and then the paper samples were repaired with the four sample adhesives and with the same method. In the next stage, the effects of the adhesives on the sample papers were studied in terms of the development of biological agents. The research results indicate that almost all adhesive samples may lead to the absorption and development of biological agents.
