Preservation of source materials

The accounting historian\u27s part in the wider preservation (i.e., keeping of old documents) is to conduct a campaign to persuade people?? this include librarians who are forced to prune their stocks of material through lack of space?? to destroy old business records or printed books until an accountant expert has examined them.Once the material has been safeguarded from destruction, whether within a larger collection or on its own, it needs to be catalogued and stored-catalogued to make it Known and to fix it (here illustrations are a great help), stored in a form which makes it easily accessible to researchers
