At the article, the hazardous elements in the repositories have been introduced and preventive measures were brought up by the author.
Damages to records break up into three major physical, biological and chemical ones such as below:
- Physical destruction, which comes from heat, humidity, light and dust
- Biological elements: micro-organisms, bacteria, fungi, moulds, insects and rodents
- Chemical damages include: chemical reactions upon paper, vellum, etc. Those
chemical reactions would occur while getting papers, covers, and non-cellulose fibers ironed or when additives add up to paper.Taking correct preventive measures, one can take away those harmful factors, and simply protect his records.
