"Interpreting Slavery at Museums and Historic Sites" is an excellent read for anyone working in (or planning to) work in the public history field. This book in the "Interpreting History" series focuses less on actionable suggestions and more on the importance of interpreting slavery. 

The inclusion of specific examples of how different locations interpret slavery, whether on tours or at special programs, is particularly interesting. There are examples not only from Southern locations but also Northern locations and a few Midwest examples as well.
