Accordions and Carousels
An accordion book, sometimes called a concertina book, is structured by folding one long sheet of paper back and forth or binding smaller sheets together then folding. The result is a book that can be read and displayed in several fashions.
A carousel book, sometimes called a star book, is another type of folded book with pages layered on top of each other for a multi-dimensional appearance. When closed, they look like a normal book but can be opened completely so that both covers touch. They resemble a star from above or a carousel from the side.
