DEFINITION
Classification: 283/52.1
Book:
(under subclass 48.1) Subject matter wherein the indicia bearing tally comprises two or more sheets secured together in overlapping arrangement only at their corresponding margins, only at a restricted field within the margins, or only at their corresponding margins and at a restricted field within the margins.
(1) Note. A folded sheet is not considered to be a book. Also, when a margin of one sheet is attached to a margin of another sheet to obtain in effect a single sheet of greater area, the resulting article is still regarded as a sheet rather than a book.
