ABSTRACT:
A circular book configuration wherein each page consists of a fixed section of a circle folded over the next adjacent page. Multiple circular book leaves are stacked on top of each other with a common center and each leaf is connected to its two adjacent leaves along the radius of the circle to form a continuous spiral or helicoidal structure, so that each page can be folded over the next page in a continuous spiraling manner from one end of the book to the other. The book is assembled in reverse order of display by starting from the top leaf, which contains the last page of the book, folding it over the next to the last page, and so on down the spiral of stacked circular leaves. When all pages are thus folded, the result is a book shaped like a pie wedge, wherein the last folded page corresponds to the first page to be viewed. The book is viewed by continuously unfolding successive pages, which results in a continuing full circular view being seen at all times.
