It provides detailed information and recommendations about various preservation methods, including mechanical copying, photographic film, magnetic recording, and optical disk recording, and on the expected useful lives of each. Also included are a method for scoring and assessing the condition of collections and a decision tree that provides a guide for orderly progress in preserving a collection of documents.
