This is a free 93 page pdf about alternatives to money with a forward written by the author of "Your Money or Your Life".  Here is the first couple of paragraphs of the introduction.

"This book is about freedomand empowerment, about community and relationships, about fairness and prosperity, but most of all it is about  money and exchange. Something extraordinary is happening to money. It is being reinvented. And this process of reinvention is sure to have far- r e a c h i n g effects on every aspect of life for everyone living in the world today.  But what is money? Where does it come from? What roles does it play? And how does money fit into the greater scheme of things? These are questions this book will address. The social, political, economic, cultural, and ecological aspects of life cannot be isolated from one another. Whatever affects one of these must, in some way and measure, affect all the others. Therefore, whatever actions we humans contemplate taking must be subjected to comprehensive evaluation. Are they generally beneficial, and are the outcomes sustainable over the long term? Will they contribute to maintaining and improving the physical environment? Will they promote healthier relationships between individuals and among different sectors of society? Will they lead to the wider fulfillment of basic human needs? Will they promote responsible citizenship? Will they promote the fuller realization of the creative potential inherent in each person and community?

The much vaunted efforts toward globalization of “free trade,” which have been pushed forward in the post–Cold War era, have failed to address these questions. They are mainly the result of an undemocratic process that gives voice only to a privileged few, who make far-reaching decisions based on questionable assumptions and limited perspectives. Those decisions, almost e n t i r e l y, reflect an emphasis on the economic benefits that would accrue to the political and financial elites in the so-called developed world and their minions in developing countries. What is promoted as “free trade” is more often an attempt to dominate markets and exploit people and resources, as giant corporate players in the game of global economy seek to continue their expansion and avoid defaulting on their debts. The drive toward territorial expansion by national governments, which characterized the global conflicts of the past century, has given way to a drive toward market expansion and profit accumulation headed by corporate and financial elites.
