The author presents a versatile technique for comparing wide binary observations with theoretical semi-major axis distributions. To illustrate this technique, the theoretical implications of the recent Latham et al. (1984) data on wide binaries are examined. Motivated by the apparent high number density of wide binaries implied by the Latham et al. sample, the author defines a criterion for selecting candidate wide binaries form the Yale Bright Star Catalog. The candidate list is used to determine an upper bound for wide binary density of nWB = 4×10-3pc-3.
