ABSTRACT:
A structure of book page for binding a book or album comprises a wide rectangular portion abutting a narrow rectangular portion, a pair of first flap members abutting two ends and a second flap portion abutting an outward side of the wide rectangular portion. Both the narrow rectangular portion and the pair of first flap members are folded upward along their predetermined folding lines and stuck up on the upper surface of the wide rectangular portion, whereas the second flap member is folded downward along a predetermined folding line and movably mats the under side of the wide rectangular portion. So that a double-layer book page is therefore accomplished with a concave strip on the upper surface and a movable convex strip on the under side along the inside margin of the book page. When binding, nest and stick up the movable convex strip of every upper page into the adjacent lower pages and bind with hard covers.
