In combination,

• a plurality of rectangular pages having mutually parallel upper and lower edges disposed one atop another to form a stack having top and bottom sheets and defining a binding edge of said stack, an opposite edge of said stack parallel to said binding edge, and a narrow binding margin on said stack adjacent to said binding edge,
• a binding for said stack including a plurality of face panels respectively overlying said top and bottom sheets of said stack and joined together by at least one spine fold located at and parallel to said binding edge of said stack, and at least one of said face panels is a narrow margin panel that extends the length of said binding margin and is limited in width so that it extends no further toward said opposite edge of said stack than said binding margin and thereby defines an inboard boundary proximate said binding margin that extends the entire distance between said upper and lower edges of said pages,
• a plurality of fasteners extending through said narrow margin panel and through said stack at said binding margin and said fasteners are located between said at least one spine fold and said inboard boundary of said margin panel, and
• a stiff, resilient, elongated clasp of uniform cross section throughout and formed as a channel-shaped structure having a pair of opposing jaws that have mutually facing surfaces which define a slot opening therebetween, and at least one of said jaws terminates in an inwardly turned hooked lip that extends the entire length of said clasp, and said clasp is disposed to capture said binding therewithin, whereby said hooked lip of said clasp engages said inboard boundary of said margin panel, thereby holding said clasp on said binding edge of said stack.

In combination,

• a plurality of rectangular sheets having mutually parallel upper and lower edges of paper disposed one atop another to form a stack having top and bottom sheets and defining a binding edge of said stack, an opposite edge parallel to said binding edge, and a narrow binding edge margin on said stack adjacent to said binding edge,
• a document binder formed of a plurality of panels including a top binding panel located atop said stack and residing in contact with said binding margin and a back binding panel joined into said top binding panel by at least one spine fold so as to extend beneath said stack and residing in contact with said binding margin thereof, wherein at least one of said top and back binding panels is a narrow binding panel and is as narrow as said binding margin and terminates in a longitudinal binding margin demarcation adjacent said narrow binding margin and parallel to said binding edge of said stack and extending between said upper and lower edges of said sheets of paper,
• at least one fastener passing through and emerging from said top and bottom sheets at said binding margin of said stack and through said narrow binding panel between said binding edge of said stack and said longitudinal binding margin demarcation of said narrow binding panel,
• an elongated document binder clasp configured as a stiff, resilient, channel-shaped structure defining a pair of mutually facing jaws that define a gap therebetween, and
• wherein at least one of said jaws has a hooked lip that extends the entire length of said clasp, and said binder clasp encompasses said binding edge of said stack and said narrow binding panel of said binding in said gap and between said jaws so that said hooked lip engages said binding margin demarcation throughout the length of said binding margin.
