Mike Curtis of the Henry George Academy has produced a series of ten videos presenting the essentials of Progress & Poverty, in a modern context. While it can’t provide the interactivity of a real-time course, it explains the important points clearly, backed up by illustrations and 21st-century data. It also provides considerable detail about how land values are assessed in Arden. The videos are on youtube and can be accessed here. In the event of youtube difficulties, the set has also been placed on the Internet Archive, beginning with Lesson 1 here.
