Investigation of indoor microclimate of historic libraries for preventive conservation of manuscripts. Case Study: Tire Necip Paşa Library, İzmir-Turkey

Results suggest that introducing a heating, ventilation and air-conditioning system to the building should be considered as the last option since natural hygrothermal behavior of the library gives reasonably sufficient evidences to prevent the manuscripts from degradations to some extent. Therefore, passive solutions should be given higher priorities not to disturb environmental past of the historic library.
