This seems to be an exhaustive study of cooperatives, particularly this side of the Atlantic, though the English, Swedish, etc. are covered in the historical survey. But primarily this book is designed to help those wanting to launch cooperatives to find the surest and soundest way to build. First the study club (here is a handbook, ready made), then credit union, buying club, cooperative stores and producing enterprises -- all covered with their rules and laws and by-laws and Constitution. There is some forecasting of further developments in the field, and both the practical and the idealistic aspects are presented.
