A stack of pages can be bound along a binding edge to form a book by positioning a first side of an elongated conductive metal foil strip in contact with the binding edge. The strip has opposed ends, opposed side edges extending between the ends, and an adhesive with a predetermined melting temperature in contact with at least a portion of a first side thereof. The strip has been altered from a first configuration to a second configuration so as to enhance a resistance of the strip between the ends from a first value to a second value substantially greater than the first value. A voltage is applied across the strip sufficient to melt the adhesive to bind the stack of pages together along the binding edge.

What is claimed is: 1. A system for binding a stack of pages along an edge thereof to form a book, the system comprising an elongated conductive metal foil strip having opposed ends and opposed side edges extending between the ends, the strip having been altered from a first configuration to a second configuration so as to enhance a resistance of the strip between the ends from a first value to a second value substantially greater than the first value, the strip further having an adhesive with a predetermined melting temperature in contact with at least a portion of a first side thereof, a portion of the strip adjacent each of the side edges uncoated with adhesive, the side edge portions foldable upward to surround the adhesive, the strip first side positionable in contact with a binding edge of a stack of pages to be bound, the strip further having end portions adjacent the ends, the end portions adapted for introducing an electrical current thereto to pass along the strip between the ends, the current sufficient to heat the strip to a temperature at least as great as the melting temperature in order to melt the adhesive and thereby bind the stack of pages together along the binding edge. 2. The system recited in claim 1, further comprising a power supply connectable to the strip end portions, the strip end portions substantially uncoated with adhesive, and wherein the strip in the first configuration has an impedance that does not match an impedance of the power supply, and the strip in the second configuration has an impedance match with the power supply. 3. The system recited in claim 2, further comprising a pair of conductive metal contacts affixable at a first end to the strip end portions and at a second end to the power supply. 4. The system recited in claim 2, wherein the power supply is adapted to provide a voltage in a range of 3-5 volts, the voltage range sufficient to heat at least a portion of the strip to the adhesive melting temperature. 5. The system recited in claim 1, wherein the adhesive is positioned in at least two sectors comprising two end sectors having a gap therebetween, the gap having a length substantially less than a length of the end sectors, the gap providing a location for excision if shortening of the strip is desired. 6. The system recited in claim 1, wherein the strip further comprises a double-sided pressure-sensitive tape adhered to a second side of the strip opposed to the first side, the tape positioned beneath each gap for providing mechanical reinforcement and further providing means for affixing the strip to an inside of a cover spine. 7. The system recited in claim 1, wherein the first resistance value comprises approximately 0.05 ohms and the second resistance value comprises approximately 0.5 ohms. 8. The system recited in claim 1, wherein the strip is longitudinally excisable if desired up to a predetermined distance from the side edges, an excision operable substantially not to alter the strip resistance. 9. The system recited in claim 1, wherein the adhesive comprises a hot-melt adhesive applicable to the strip in solid form. 10. 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. 11. 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 conductive metal foil 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, and an adhesive with a predetermined melting temperature in contact with at least a portion of a first side thereof, the strip having been altered from a first configuration to a second configuration so as to enhance a resistance of the strip between the ends from a first value to a second value substantially greater than the first value; and applying a voltage across the strip sufficient to melt the adhesive to bind the stack of pages together along the binding edge. 12. The method recited in claim 11, 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. 13. The method recited in claim 11, further comprising the step, prior to the voltage-applying step, of folding a portion of the strip adjacent each of the side edges upward to surround the adhesive, the folded portions substantially without adhesive in contact therewith. 14. The method recited in claim 11, further comprising the steps, prior to the voltage-applying step, of: adhering a double-sided pressure-sensitive tape to a second side of the strip opposed to the first side, and affixing the strip second side to an inside of a cover spine. 15. A book-binding element comprising an elongated conductive metal foil strip having: opposed ends and opposed side edges extending between the ends, the strip having been altered from a first configuration to a second configuration so as to enhance a resistance of the strip between the ends from a first value to a second value substantially greater than the first value, the strip further having an adhesive with a predetermined melting temperature in contact with at least a central portion of a first side thereof in spaced relation from the ends, a portion of the strip adjacent each of the side edges uncoated with adhesive, the side portions foldable upward to surround the adhesive, the strip further having opposed end portions on either side of the central portion, the end portions substantially uncoated with adhesive, the strip first side positionable in contact with a binding edge of a stack of pages to be bound, the strip in the second configuration impedance-matched with a power supply for delivering current along the strip between the end portions sufficient to heat the strip to a temperature at least as great as the melting temperature in order to melt the adhesive and thereby bind the stack of pages together along the binding edge. 16. A method of making a book-binding element comprising the steps of: altering an elongated conductive metal foil strip from a first configuration to a second configuration so as to enhance a resistance of the strip between opposed ends from a first value to a second value substantially greater than the first value; and applying an adhesive with a predetermined melting temperature to at least a portion of a first side of the strip, the strip first side positionable in contact with a binding edge of a stack of pages to be bound, the strip in the second configuration impedance-matched with a power supply for delivering current along the strip between the ends sufficient to heat the strip to a temperature at least as great as the melting temperature in order to melt the adhesive and thereby bind the stack of pages together along the binding edge. 17. The method recited in claim 16, wherein the adhesive-applying step comprises applying the adhesive to a central portion in spaced relation from the ends, opposed end portions on either side of the central portion substantially uncoated with adhesive. 18. The method recited in claim 16, wherein the adhesive-applying step comprises avoiding applying the adhesive a portion of the strip adjacent each of the side edges, the side edge portions foldable upward to surround the adhesive. 19. The method recited in claim 16, wherein the first resistance value comprises approximately 0.05 ohms and the second resistance value comprises approximately 0.5 ohms. 20. The method recited in claim 16, further comprising the step of excising the longitudinally up to a predetermined distance from the side edges, an excision operable substantially not to alter the strip resistance. 21. The method recited in claim 16, wherein the applying step comprises applying a hot-melt adhesive to the strip in solid form.
