The Catalogue of Nearby Stars (Gliese, 1969) contains 1529 single stars and systems with altogether 1890 components. It includes 54 white dwarfs with apparent magnitudes from 8.5 to 17; namely 38 single stars and 16 degenerate stars which are components of binaries or triples. Only 48 of these objects have parallaxes larger than 0″.050. But our knowledge is very incomplete.
