Abstract
This paper describes an exact limit procedure by which a simple formula for the N-double-pole solution to the difference-difference KdV equation is derived from its 2N-soliton solution in Hirota's form. This limit procedure is general and can apply to other soliton equations with multi-soliton solutions in Hirota's form.
