The Canadian Conservation Institute has released The ABC Method: A Risk Management Approach to the Preservation of Cultural Heritage.
Here's an excerpt:
This manual offers a comprehensive understanding of risk management applied to the preservation of heritage assets, whether collections, buildings or sites. It provides a step-by-step procedure and a variety of tools to guide the heritage professional in applying the ABC method to their own context. The method can be applied to a range of situations, from analysis of a single risk to a comprehensive risk assessment of the entire heritage asset.
