In addition to being available in the book store, the publisher of the text is also selling an electronic version of the text book. This is available immediately, and costs $77.70. If you are interested in purchasing the e-book, instructions for download are uploaded in the ‘Handouts’ section.
For your reference (I think you need this when you’re buying the book), the ISBN for the e-book is 0-390-896276.
Please note: The ISBN for the book is unique because it’s a special printing of the text. I know that several of you have already bought the text book from other sources, and that’s fine. Don’t panic if you don’t find this ISBN on Amazon or elsewhere – it’s still Macroeconomics (2e) by Delong and Olney.
