A folding book is a book or pamphlet typified by a continuous unbound paper sheet, folded as to form folios. A folding book folded in repeated parallel alternating folds, in the fashion of an accordion pleat, is further known as a concertina, accordion, or leporello. [1] [2]
The style of folding is similar to that of the air bellows of a concertina or the eponymous accordion, such that every written page faces another written page when the book is closed. It may therefore be opened to any page. [3] It may have a cover attached to the front and back end sections of the book, or holes in the back cover to allow the book to be "laced." [4]
A folding-book manuscript is from one of many pre-modern hand-written folding book traditions. [5]
folded (folding) book. A form of book consisting of a long strip of paper folded "concertina-wise" and attached at one or both ends to stiff covers. The "folded book" is common in the Orient but much less so in other parts of the world, except in books of an unusual nature, such as books of a pictorial nature with views of places and/or panoramas.
