A stack of pages is bound along a first edge to form a book using an elongated resistive strip having an adhesive in contact with at least a portion of a first side. The strip has two opposed ends and is dimensioned to substantially cover the first edge of the stack, with the first side against the first edge of the stack. Preferably the strip has a series of alternating finely scribed, spaced-apart cuts extending through the foil. An electrical current is introduced to pass along the strip between the ends. The current should be sufficient to create enough heat in the strip to achieve a temperature at least as great as the adhesive's melting temperature, enabling the melted adhesive to bind the stack of pages together along the first edge.

The system recited in claim 1, further comprising a generally squared-"U"-shaped holder having a gap between two arms thereof, the gap having a width sufficient to admit the page stack and a cover. 16. The system recited in claim 1, wherein the electrical current introducing means comprises a power supply and a switch in electrical connection between the power supply and the strip ends, the switch having an "on" position for activating the power supply and an "off" position for deactivating the power supply. 17. A method for binding a stack of pages along an edge thereof to form a book, the method comprising the steps of: positioning a first side of an elongated strip in contact with a binding edge of a stack of pages desired to be bound, the strip having: opposed ends; opposed side edges extending between the ends; an electrical resistivity between the ends; a plurality of spaced-apart cuts extending therethrough inwardly from and perpendicular to the side edges in alternating fashion, so as to form a substantially serpentine electrically conductive path between the ends; and an adhesive with a predetermined melting temperature in contact with at least a portion of a first side thereof; and melting the adhesive to bind the stack of pages together along the binding edge. 18. The method recited in claim 17, wherein the melting step comprises introducing an electrical current along the strip between the ends, the current sufficient to heat the strip to a temperature at least as great as the melting temperature. 19. The method recited in claim 17, wherein the electrical current introducing step comprises affixing a pair of conductive metal contacts to the strip end portions and flowing an electrical current across the strip between the ends thereof. 20.
