Collection and Storage of Documents:
From the dawn of civilisation man has recognised the need for collecting and preserving the records of human thought. Books and other graphic material are the records of human thoughts, action and achievement and can serve as the basis for future achievement. Their value to society, thus, cannot be exaggerated. These records are collected and preserved in libraries for the benefit of present and future generations. These records, diverse in form and content, are referred to by the generic term documents.
