I came across a nice description of Henry George's book "Social Problems" and thought it worth sharing here:
This work of Henry George is one of the best to give to someone who has no knowledge whatever of the Georgist philosophy. It consists of 22 essays written in George's down-to-earth language and deals with problems which exist in all generations such as "The Rights of Man," "Public Debts and Indirect Taxation," "The Functions of Government," and "The Increasing Importance of Social Questions."
He tells in such simple and direct language "What We Must Do" about the land problem that it should arouse interest on the part of one knowing nothing of the land question to find out more about it and hopefully become involved in our work.
You can find these chapters online here, with a list of some of the themes in each one.
