Colorado, Illinois, Indiana, Ohio, Wisconsin and New York have similar programs. Farm-oriented museums and events are located throughout North America. Usually the staffs are knowledgeable in interpreting farm buildings of different types and periods. In this age of the Internet, books and videos are holding their own. I have a number of videos in my collection that feature barn raisings or the efforts of a barn preservation group.
Videos are available at many farm-oriented museums.
Agricultural extension services at state universities will at the least have staff who can furnish leads. At best the school will have personnel who are expert in barn preservation and can recommend technical and human resources in your area. Ames are excellent examples of these resources. Historical societies are organized on every level of government-from the state to the township and village. Some are general in nature while others were founded to save a specific building.
