ABSTRACT:
The improved notebook and notebook cover assembly of the present invention includes a notebook, preferably of a loose-leaf type, and a sub-assembly which includes front and rear notebook covers, an edge binder interconnecting the two covers and foldable back upon itself, and a notebook connector releasably interconnecting the notebook only to the covers. Due to the edge binder the covers are movable between a first position wherein the front cover overlies and protects the notebook and a second position wherein the front cover is behind and flat against the rear cover, thus fully exposing the notebook and supporting it in a flat position for easy viewing and writing therein. The edge binder can have a longitudinal fold line along the length of the center line of the central portion thereof, or can be divided along that center line into two halves joined together by a hinge, such as a piano hinge or a flexible strip of plastic, cloth, paper or rubber. Openable rings or the like releasably secure the notebook to the covers, either directly thereto or to wings connected to the inner surfaces of the covers. If desired, the edge binder can be integral with the covers. Detents may be present on the covers to releasably hold them together when the front cover is in the second position.
