The paperback edition of Interest Rate Cycles: An Introduction is now available at Amazon.com. It will be available online at other booksellers (including local Amazon stores), or by special order in brick and mortar stores, over the coming days/weeks. (The ISBN is 978-0-9947480-4-1)
It will take time for the "Look Inside" feature to be set up on the Amazon web site; you will need to look at the ebook page for now.
The book may be ordered directly from CreateSpace (the printer); the discount code S6AKAJNZ reduces the price by 20% (code only works only at Createspace!). (I believe that the CreateSpace store ships all of these orders from the United States.)
The paperback edition is 102 pages, excluding front matter.
Having worked out many of the kinks of paperback production, the paperback edition of Understanding Government Finance should be published relatively soon.
