1. The visitors should appear only in special areas. They are usually kept out from storage rooms, treatment rooms etc. Exposition and reading rooms are something different, but the most valuable objects could be provided with individual cases with climate control. On the other hand - use of copies, replicas etc. is a good idea for "mass events" when the clue is not the objects from the collections.
2. In normal library use the reading rooms provide rather stable conditions of temperature, RH and microbial presence. The reading rooms for special collections are usually less occupied. Should there be a significant difference in T&RH between storage and reading rooms, transition rooms for conditioning and stabilization of objects should be provided.
