This is the fourth, and last, in a series of compilations by Robert Harbin, a pioneer of paper-folding in the West. Sadly, shortly after it was printed the publisher decided to discontinue the series, and now this book, as well as the 3rd in the series, are very hard to find. The only version of the book still in print is the Hebrew one, printed in Israel by "Ledori".

The book is an excellent showcase of the international origami talent in 1977, containing works from leading folders such as Neal Elias, Fred Rohm, Patricia Crawford, John Richardson, Max Hulme, Martin Wall and more, and even a couple of works from a young Ronald Koh. Many of the models are of highly original subjects not often seen in origami.

The diagramming style can be very concise and challenging at times, having many steps appear in one drawing, I believe it is still accessible, though, and that this book is well worth the effort for the originality of the models within.

The Hebrew version of this book is still in print. You can get it here (website is in Hebrew).
