There are no unions for historic preservationists, but those interested in the field can look into professional organizations such as the National Preservation Institute, which offers continuing education classes and information on networking opportunities, and the National Council for Preservation Education, which helps prospective students identify quality historic preservation education degree programs in the United States. Historic preservations at the state and local organizations also provide useful resources.
