Scientific paper

Identifications are provided for 103 bright Luyten common proper motion (CPM) stellar systems (mpg < 17.0) containing likely white dwarf (WD) components. New spectral types are presented for 55 components, and spectral types for 51 more are available in the literature. With the CPM systems previously published by Giclas and collaborators, the Luyten stars provide a uniform sample of nearly 200 pairs or multiples brighter than 17th magnitude. Selection effects biasing the combined samples are discussed; in parituclar the authors present evidence that fewer than 1% of wide WD binaries have been detected.
