The cover of Ken Macrorie's textbook, The I-Search Paper, has a moebius strip on it, reflecting this sentiment nicely.<br>

But the conceit of the moebius strip extends from the back cover as well

So, you start reading this book on the back cover, nice twist, just like in a moebius strip. You work through the text by doing. Then when you are done, you get to the end and out the back of the book you go onto the back cover, to enter again. Escher would approve. That is what I see happening here. In the end this process serves the product, the text that is produced for anyone concerned.
