The Care and Handling of Recorded Sound Materials
Source: National Library of Canada via CoOL
Sound recordings are machine readable artifacts; they are documents for which the integrity of the information they contain is directly related to the artifacts’ physical well being. Since the majority of sound recordings are made of plastic, conservation must be treated as a plastics degradation problem, requiring a different approach than paper conservation. It is important to understand the basic chemical degenerative processes and the principles of the retention of sound by the various media in order to ensure that proper action is taken to slow the rate of degradation.
