The Canadian Conservation Institute published a technical bulletin, #23, in 2000 entitled: "Guidelines for Humidity and Temperature for Canadian Archives" which deals authoritatively on the subject, as well as other unstable media - the bulletin costs about $ 6.00 US and may be ordered through their website www.cci-icc.gc.ca

Hello!
    Does anyone know what a reasonable level of humidity is in climate-controlled archives?  The contents consist mostly of wooden furniture or paper documents. Any help would be greatly appreciated!
