SECTION I - CLASS DEFINITION

Books, strips, and leaves and various combinations thereof, combinations thereof with other things for which no other place is provided, processes of making where the processes are fully disclosed in the articles, and accessories to books, strips, and leaves, such as protectors, book-leaf holders and marks, and holders, therefor, for which no other place is provided.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

Leaf arrangements which merely facilitate removal of a leaf from an arrangement or package are found in Class 206, Special Receptacle or Package, subclasses 449+; the inclusion of means to separate a leaf from the residue so that it may be dispensed and will effect classification in Class 221, Article Dispensing. A permanently bound book with leaf perforations for leaf removal is found in this class (281).

A sheet retention means providing nondestructive sheet recovery therefrom in combination with the sheet mounted thereon and where such sheet in addition includes structure (e.g., line of perforations, etc.), permitting destructive recovery of a portion thereof is placed in Class 402, Binder Device Releasably Engaging Aperture or Notch of Sheet.

SECTION IV - GLOSSARY

BOOK

Consists of two or more sheets secured together (a) only at their margins or (b) only at a restricted field within the margins or (c) only at their margins and at a restricted field within the margins. A folded sheet has not been classified as a book. 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.

LEAF

A sheet other than a strip.

SHEET

A body having two parallel surfaces both dimensions of which are large in comparison with the third dimension of the body.

STRIP

A sheet folded back and forth along at least two fold lines and unattached to anything or attached to a backing either at the ends only or in such a way that the folded portions can be successively released without mutilation, or it is a sheet rolled up. Also patents claiming fold lines or other features for so folding or rolling up sheets are classified as "strips".
